OriginAccessIdentity (string) --
The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:
origin-access-identity/cloudfront/ID-of-origin-access-identity
where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.
If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.
CustomOriginConfig (dict) --
Use this type to specify an origin that is a content container or HTTP server, including an Amazon S3 bucket that is configured with static website hosting. To specify an Amazon S3 bucket that is not configured with static website hosting, use the S3OriginConfig type instead.

Items (list) --
A list that contains allowed SSL/TLS protocols for this distribution.
(string) --
OriginReadTimeout (integer) --
Specifies how long, in seconds, CloudFront waits for a response from the origin. This is also known as the origin response timeout. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 30 seconds.
For more information, see Origin Response Timeout in the Amazon CloudFront Developer Guide.
OriginKeepaliveTimeout (integer) --
Specifies how long, in seconds, CloudFront persists its connection to the origin. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 5 seconds.

The number of times that CloudFront attempts to connect to the origin. The minimum number is 1, the maximum is 3, and the default (if you don’t specify otherwise) is 3.
For a custom origin (including an Amazon S3 bucket that’s configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout.
For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide.
ConnectionTimeout (integer) --
The number of seconds that CloudFront waits when trying to establish a connection to the origin. The minimum timeout is 1 second, the maximum is 10 seconds, and the default (if you don’t specify otherwise) is 10 seconds.

TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.
TrustedSigners (dict) --
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.
Enabled (boolean) --
Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.
Quantity (integer) --
The number of trusted signers for this cache behavior.
Items (list) --

A complex type that contains the HTTP methods that you want CloudFront to cache responses to.
(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --

viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) --
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) --

For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
ErrorCode (integer) --
The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.

ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.

Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
The Web ACL Id (if any) associated with the distribution.
HttpVersion (string) --
Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 will automatically use an earlier version.
IsIPV6Enabled (boolean) --
Whether CloudFront responds to IPv6 DNS requests with an IPv6 address for your distribution.
AliasICPRecordals (list) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
(dict) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can't configure it yourself.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
CNAME (string) --
A domain name associated with a distribution.
ICPRecordalStatus (string) --
The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.
The status values returned are the following:
APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.
SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.
PENDING indicates that CloudFront can't determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.

CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

If you want to send values to the origin but not include them in the cache key, use an OriginRequestPolicy. See CreateOriginRequestPolicy.
A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.
QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.

Items (list) --
Optional: A complex type that contains cache behaviors for this distribution. If Quantity is 0, you can omit Items.
(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) --
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) --

The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. You can specify the following options:
allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).
Items (list) --
A complex type that contains the HTTP methods that you want CloudFront to process and forward to your origin.
(string) --
CachedMethods (dict) --

CloudFront caches responses to GET and HEAD requests.
CloudFront caches responses to GET, HEAD, and OPTIONS requests.
If you pick the second choice for your Amazon S3 Origin, you may need to forward Access-Control-Request-Method, Access-Control-Request-Headers, and Origin headers for the responses to be cached correctly.
Quantity (integer) --
The number of HTTP methods for which you want CloudFront to cache responses. Valid values are 2 (for caching responses to GET and HEAD requests) and 3 (for caching responses to GET, HEAD, and OPTIONS requests).
Items (list) --
A complex type that contains the HTTP methods that you want CloudFront to cache responses to.
(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) --
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) --
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) --
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) --
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) --
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) --
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --

Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
ETag (string) --
The current version of the configuration. For example: E2QWRUHAPOMQZL.
Gets a list of distribution IDs for distributions that have a cache behavior that’s associated with the specified cache policy.
You can optionally specify the maximum number of items to receive in the response. If the total number of items in the list exceeds the maximum that you specify, or the default maximum, the response is paginated. To get the next page of items, send a subsequent request that specifies the NextMarker value from the current response as the Marker value in the subsequent request.

Creates a cache policy.
After you create a cache policy, you can attach it to one or more cache behaviors. When it’s attached to a cache behavior, the cache policy determines the following:
The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.
The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.
The headers, cookies, and query strings that are included in the cache key are automatically included in requests that CloudFront sends to the origin. CloudFront sends a request when it can’t find an object in its cache that matches the request’s cache key. If you want to send values to the origin but not include them in the cache key, use CreateOriginRequestPolicy.
For more information about cache policies, see Controlling the cache key in the Amazon CloudFront Developer Guide.

[REQUIRED]
A cache policy configuration.
Comment (string) --
A comment to describe the cache policy.
Name (string) -- [REQUIRED]
A unique name to identify the cache policy.
DefaultTTL (integer) --
The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object’s time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.
MaxTTL (integer) --
The maximum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.
MinTTL (integer) -- [REQUIRED]
The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
ParametersInCacheKeyAndForwardedToOrigin (dict) --
The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are automatically included in requests that CloudFront sends to the origin.
EnableAcceptEncodingGzip (boolean) -- [REQUIRED]
A flag that determines whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
If this field is true and the viewer request includes the Accept-Encoding header, then CloudFront normalizes the value of the viewer’s Accept-Encoding header to one of the following:
Accept-Encoding: gzip (if gzip is in the viewer’s Accept-Encoding header)
Accept-Encoding: identity (if gzip is not in the viewer’s Accept-Encoding header)
CloudFront includes the normalized header in the cache key and includes it in requests that CloudFront sends to the origin.
If this field is false, then CloudFront treats the Accept-Encoding header the same as any other HTTP header in the viewer request. By default, it’s not included in the cache key and it’s not included in origin requests. You can manually add Accept-Encoding to the headers whitelist like any other HTTP header.
When this field is true, you should not whitelist the Accept-Encoding header in the cache policy or in an origin request policy attached to the same cache behavior.
For more information, see Cache compressed objects in the Amazon CloudFront Developer Guide.

CallerReference (string) --
A value that you specify to uniquely identify an invalidation request. CloudFront uses the value to prevent you from accidentally resubmitting an identical request. Whenever you create a new invalidation request, you must specify a new value for CallerReference and change other values in the request as applicable. One way to ensure that the value of CallerReference is unique is to use a timestamp, for example, 20120301090000.
If you make a second invalidation request with the same value for CallerReference, and if the rest of the request is the same, CloudFront doesn't create a new invalidation request. Instead, CloudFront returns information about the invalidation request that you previously created with the same CallerReference.
If CallerReference is a value you already sent in a previous invalidation batch request but the content of any Path is different from the original request, CloudFront returns an InvalidationBatchAlreadyExists error.

Distribution (dict) --
The distribution's information.
Id (string) --
The identifier for the distribution. For example: EDFDVBD632BHDS5.
ARN (string) --
The ARN (Amazon Resource Name) for the distribution. For example: arn:aws:cloudfront::123456789012:distribution/EDFDVBD632BHDS5, where 123456789012 is your AWS account ID.
Status (string) --
This response element indicates the current status of the distribution. When the status is Deployed, the distribution's information is fully propagated to all CloudFront edge locations.

The number of invalidation batches currently in progress.
DomainName (string) --
The domain name corresponding to the distribution, for example, d111111abcdef8.cloudfront.net.
ActiveTrustedSigners (dict) --
CloudFront automatically adds this element to the response only if you've set up the distribution to serve private content with signed URLs. The element lists the key pair IDs that CloudFront is aware of for each trusted signer. The Signer child element lists the AWS account number of the trusted signer (or an empty Self element if the signer is you). The Signer element also includes the IDs of any active key pairs associated with the trusted signer's AWS account. If no KeyPairId element appears for a Signer, that signer can't create working signed URLs.
Enabled (boolean) --
Enabled is true if any of the AWS accounts listed in the TrustedSigners complex type for this distribution have active CloudFront key pairs. If not, Enabled is false.
Quantity (integer) --
The number of trusted signers specified in the TrustedSigners complex type.
Items (list) --
A complex type that contains one Signer complex type for each trusted signer that is specified in the TrustedSigners complex type.

DistributionConfig (dict) --
The current configuration information for the distribution. Send a GET request to the /CloudFront API version/distribution ID/config resource.
CallerReference (string) --
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.
If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.
If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.
Aliases (dict) --
A complex type that contains information about CNAMEs (alternate domain names), if any, for this distribution.
Quantity (integer) --
The number of CNAME aliases, if any, that you want to associate with this distribution.
Items (list) --
A complex type that contains the CNAME aliases, if any, that you want to associate with this distribution.

DefaultRootObject (string) --
The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution ( http://www.example.com) instead of an object in your distribution ( http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.
Specify only the object name, for example, index.html. Don't add a / before the object name.
If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.
To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.

TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.
TrustedSigners (dict) --
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.

A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

A complex type that contains the HTTP methods that you want CloudFront to cache responses to.
(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

LambdaFunctionARN (string) --
The ARN of the Lambda function. You must specify the ARN of a function version; you can't specify a Lambda alias or $LATEST.
EventType (string) --
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.
IncludeBody (boolean) --
A flag that allows a Lambda function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.
FieldLevelEncryptionId (string) --
The value of ID for the field-level encryption configuration that you want CloudFront to use for encrypting specific fields of data for the default cache behavior.
CachePolicyId (string) --
The unique identifier of the cache policy that is attached to the default cache behavior. For more information, see CachePolicy.
OriginRequestPolicyId (string) --
The unique identifier of the origin request policy that is attached to the default cache behavior. For more information, see OriginRequestPolicy.
ForwardedValues (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include values in the cache key, use a CachePolicy. See CreateCachePolicy.
If you want to send values to the origin but not include them in the cache key, use an OriginRequestPolicy. See CreateOriginRequestPolicy.
A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.
QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.
Cookies (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.
Forward (string) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.
Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.
WhitelistedNames (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Required if you specify whitelist for the value of Forward. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.
If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.
For the current limit on the number of cookie names that you can whitelist for each cache behavior, see CloudFront Limits in the AWS General Reference.
Quantity (integer) --
The number of cookie names in the Items list.
Items (list) --
A list of cookie names.
(string) --
Headers (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include headers in the cache key, use HeadersConfig in a cache policy. See CreateCachePolicy.
If you want to send headers to the origin but not include them in the cache key, use HeadersConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies the Headers, if any, that you want CloudFront to forward to the origin for this cache behavior (whitelisted headers). For the headers that you specify, CloudFront also caches separate versions of a specified object that is based on the header values in viewer requests.
For more information, see Caching Content Based on Request Headers in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of header names in the Items list.
Items (list) --
A list of HTTP header names.
(string) --
QueryStringCacheKeys (dict) --

MinTTL (integer) --
This field is deprecated. We recommend that you use the MinTTL field in CachePolicyConfig instead of this field.
The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers, if you specify 1 for Quantity and * for Name).
DefaultTTL (integer) --
This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
CacheBehaviors (dict) --
A complex type that contains zero or more CacheBehavior elements.
Quantity (integer) --
The number of cache behaviors for this distribution.
Items (list) --
Optional: A complex type that contains cache behaviors for this distribution. If Quantity is 0, you can omit Items.
(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) --
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) --
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.
Enabled (boolean) --
Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.
Quantity (integer) --
The number of trusted signers for this cache behavior.
Items (list) --
Optional: A complex type that contains trusted signers for this cache behavior. If Quantity is 0, you can omit Items.
(string) --
ViewerProtocolPolicy (string) --
The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. You can specify the following options:
allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).
Items (list) --
A complex type that contains the HTTP methods that you want CloudFront to process and forward to your origin.
(string) --
CachedMethods (dict) --
A complex type that controls whether CloudFront caches the response to requests using the specified HTTP methods. There are two choices:
CloudFront caches responses to GET and HEAD requests.
CloudFront caches responses to GET, HEAD, and OPTIONS requests.
If you pick the second choice for your Amazon S3 Origin, you may need to forward Access-Control-Request-Method, Access-Control-Request-Headers, and Origin headers for the responses to be cached correctly.
Quantity (integer) --
The number of HTTP methods for which you want CloudFront to cache responses. Valid values are 2 (for caching responses to GET and HEAD requests) and 3 (for caching responses to GET, HEAD, and OPTIONS requests).
Items (list) --
A complex type that contains the HTTP methods that you want CloudFront to cache responses to.
(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.
LambdaFunctionAssociations (dict) --
A complex type that contains zero or more Lambda function associations for a cache behavior.
Quantity (integer) --
The number of Lambda function associations for this cache behavior.
Items (list) --
Optional: A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0, you can omit Items.
(dict) --
A complex type that contains a Lambda function association.
LambdaFunctionARN (string) --
The ARN of the Lambda function. You must specify the ARN of a function version; you can't specify a Lambda alias or $LATEST.
EventType (string) --
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.
IncludeBody (boolean) --
A flag that allows a Lambda function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.
FieldLevelEncryptionId (string) --
The value of ID for the field-level encryption configuration that you want CloudFront to use for encrypting specific fields of data for this cache behavior.
CachePolicyId (string) --
The unique identifier of the cache policy that is attached to this cache behavior. For more information, see CreateCachePolicy.
OriginRequestPolicyId (string) --
The unique identifier of the origin request policy that is attached to this cache behavior. For more information, see CreateOriginRequestPolicy.
ForwardedValues (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include values in the cache key, use a CachePolicy. See CreateCachePolicy.
If you want to send values to the origin but not include them in the cache key, use an OriginRequestPolicy. See CreateOriginRequestPolicy.
A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.
QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.
Cookies (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.
Forward (string) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.
Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.
WhitelistedNames (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Required if you specify whitelist for the value of Forward. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.
If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.
For the current limit on the number of cookie names that you can whitelist for each cache behavior, see CloudFront Limits in the AWS General Reference.
Quantity (integer) --
The number of cookie names in the Items list.
Items (list) --
A list of cookie names.
(string) --
Headers (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include headers in the cache key, use HeadersConfig in a cache policy. See CreateCachePolicy.
If you want to send headers to the origin but not include them in the cache key, use HeadersConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies the Headers, if any, that you want CloudFront to forward to the origin for this cache behavior (whitelisted headers). For the headers that you specify, CloudFront also caches separate versions of a specified object that is based on the header values in viewer requests.
For more information, see Caching Content Based on Request Headers in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of header names in the Items list.
Items (list) --
A list of HTTP header names.
(string) --
QueryStringCacheKeys (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use an QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that contains information about the query string parameters that you want CloudFront to use for caching for this cache behavior.
Quantity (integer) --
The number of whitelisted query string parameters for a cache behavior.
Items (list) --
A list that contains the query string parameters that you want CloudFront to use as a basis for caching for a cache behavior. If Quantity is 0, you can omit Items.
(string) --
MinTTL (integer) --
This field is deprecated. We recommend that you use the MinTTL field in CachePolicyConfig instead of this field.
The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers, if you specify 1 for Quantity and * for Name).
DefaultTTL (integer) --
This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
CustomErrorResponses (dict) --
A complex type that controls the following:
Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.
How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of HTTP status codes for which you want to specify a custom error page and/or a caching duration. If Quantity is 0, you can omit Items.
Items (list) --
A complex type that contains a CustomErrorResponse element for each HTTP status code for which you want to specify a custom error page and/or a caching duration.
(dict) --
A complex type that controls:
Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.
How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
ErrorCode (integer) --
The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) --
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) --
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) --
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) --
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) --
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) --
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
AliasICPRecordals (list) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
(dict) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can't configure it yourself.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
CNAME (string) --
A domain name associated with a distribution.
ICPRecordalStatus (string) --
The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.
The status values returned are the following:
APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.
SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.
PENDING indicates that CloudFront can't determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.
ETag (string) --
The current version of the distribution's information. For example: E2QWRUHAPOMQZL.
Gets a list of distribution IDs for distributions that have a cache behavior that’s associated with the specified origin request policy.
You can optionally specify the maximum number of items to receive in the response. If the total number of items in the list exceeds the maximum that you specify, or the default maximum, the response is paginated. To get the next page of items, send a subsequent request that specifies the NextMarker value from the current response as the Marker value in the subsequent request.

DomainName (string) --
The DNS name of the Amazon S3 origin.
OriginAccessIdentity (string) --
The CloudFront origin access identity to associate with the distribution. Use an origin access identity to configure the distribution so that end users can only access objects in an Amazon S3 bucket through CloudFront.
If you want end users to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information, see Using an Origin Access Identity to Restrict Access to Your Amazon S3 Content in the Amazon CloudFront Developer Guide.

CallerReference (string) -- [REQUIRED]
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.
If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.
If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.
Aliases (dict) --

The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution ( http://www.example.com) instead of an object in your distribution ( http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.
Specify only the object name, for example, index.html. Don't add a / before the object name.
If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.
To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.
To replace the default root object, update the distribution configuration and specify the new object.
For more information about the default root object, see Creating a Default Root Object in the Amazon CloudFront Developer Guide.

https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) -- [REQUIRED]
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

EventType (string) -- [REQUIRED]
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.
IncludeBody (boolean) --
A flag that allows a Lambda function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.
FieldLevelEncryptionId (string) --

ForwardedValues (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include values in the cache key, use a CachePolicy. See CreateCachePolicy.
If you want to send values to the origin but not include them in the cache key, use an OriginRequestPolicy. See CreateOriginRequestPolicy.
A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.
QueryString (boolean) -- [REQUIRED]
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.
Forward (string) -- [REQUIRED]
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.
Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.
WhitelistedNames (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Required if you specify whitelist for the value of Forward. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.
If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.
For the current limit on the number of cookie names that you can whitelist for each cache behavior, see CloudFront Limits in the AWS General Reference.
Quantity (integer) -- [REQUIRED]
The number of cookie names in the Items list.
Items (list) --
A list of cookie names.
(string) --

If you want to include headers in the cache key, use HeadersConfig in a cache policy. See CreateCachePolicy.
If you want to send headers to the origin but not include them in the cache key, use HeadersConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies the Headers, if any, that you want CloudFront to forward to the origin for this cache behavior (whitelisted headers). For the headers that you specify, CloudFront also caches separate versions of a specified object that is based on the header values in viewer requests.
For more information, see Caching Content Based on Request Headers in the Amazon CloudFront Developer Guide.
Quantity (integer) -- [REQUIRED]
The number of header names in the Items list.
Items (list) --
A list of HTTP header names.
(string) --
QueryStringCacheKeys (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use an QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.

The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers, if you specify 1 for Quantity and * for Name).
DefaultTTL (integer) --
This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
CacheBehaviors (dict) --

The number of cache behaviors for this distribution.
Items (list) --
Optional: A complex type that contains cache behaviors for this distribution. If Quantity is 0, you can omit Items.
(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) -- [REQUIRED]
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) -- [REQUIRED]
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.

Optional: A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0, you can omit Items.
(dict) --
A complex type that contains a Lambda function association.
LambdaFunctionARN (string) -- [REQUIRED]
The ARN of the Lambda function. You must specify the ARN of a function version; you can't specify a Lambda alias or $LATEST.
EventType (string) -- [REQUIRED]
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.
IncludeBody (boolean) --
A flag that allows a Lambda function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.
FieldLevelEncryptionId (string) --
The value of ID for the field-level encryption configuration that you want CloudFront to use for encrypting specific fields of data for this cache behavior.
CachePolicyId (string) --
The unique identifier of the cache policy that is attached to this cache behavior. For more information, see CreateCachePolicy.
OriginRequestPolicyId (string) --
The unique identifier of the origin request policy that is attached to this cache behavior. For more information, see CreateOriginRequestPolicy.
ForwardedValues (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include values in the cache key, use a CachePolicy. See CreateCachePolicy.
If you want to send values to the origin but not include them in the cache key, use an OriginRequestPolicy. See CreateOriginRequestPolicy.
A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.
QueryString (boolean) -- [REQUIRED]
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.
Cookies (dict) -- [REQUIRED]
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.
Forward (string) -- [REQUIRED]
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.
Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.
WhitelistedNames (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Required if you specify whitelist for the value of Forward. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.
If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.
For the current limit on the number of cookie names that you can whitelist for each cache behavior, see CloudFront Limits in the AWS General Reference.
Quantity (integer) -- [REQUIRED]
The number of cookie names in the Items list.
Items (list) --
A list of cookie names.
(string) --
Headers (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include headers in the cache key, use HeadersConfig in a cache policy. See CreateCachePolicy.
If you want to send headers to the origin but not include them in the cache key, use HeadersConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies the Headers, if any, that you want CloudFront to forward to the origin for this cache behavior (whitelisted headers). For the headers that you specify, CloudFront also caches separate versions of a specified object that is based on the header values in viewer requests.
For more information, see Caching Content Based on Request Headers in the Amazon CloudFront Developer Guide.
Quantity (integer) -- [REQUIRED]
The number of header names in the Items list.
Items (list) --
A list of HTTP header names.
(string) --
QueryStringCacheKeys (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use an QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that contains information about the query string parameters that you want CloudFront to use for caching for this cache behavior.
Quantity (integer) -- [REQUIRED]
The number of whitelisted query string parameters for a cache behavior.
Items (list) --
A list that contains the query string parameters that you want CloudFront to use as a basis for caching for a cache behavior. If Quantity is 0, you can omit Items.
(string) --
MinTTL (integer) --
This field is deprecated. We recommend that you use the MinTTL field in CachePolicyConfig instead of this field.
The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers, if you specify 1 for Quantity and * for Name).
DefaultTTL (integer) --
This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
CustomErrorResponses (dict) --
A complex type that controls the following:
Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.
How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Quantity (integer) -- [REQUIRED]
The number of HTTP status codes for which you want to specify a custom error page and/or a caching duration. If Quantity is 0, you can omit Items.
Items (list) --
A complex type that contains a CustomErrorResponse element for each HTTP status code for which you want to specify a custom error page and/or a caching duration.
(dict) --
A complex type that controls:
Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.
How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
ErrorCode (integer) -- [REQUIRED]
The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) -- [REQUIRED]
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) -- [REQUIRED]
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) -- [REQUIRED]
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) -- [REQUIRED]
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) -- [REQUIRED]
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) -- [REQUIRED]
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) -- [REQUIRED]
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) -- [REQUIRED]
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) -- [REQUIRED]
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.

QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.
Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.
WhitelistedNames (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.

You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.

origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.
IncludeBody (boolean) --
A flag that allows a Lambda function to have read access to the body content. For more information, see Accessing the Request Body by Choosing the Include Body Option in the Amazon CloudFront Developer Guide.
FieldLevelEncryptionId (string) --
The value of ID for the field-level encryption configuration that you want CloudFront to use for encrypting specific fields of data for this cache behavior.
CachePolicyId (string) --
The unique identifier of the cache policy that is attached to this cache behavior. For more information, see CreateCachePolicy.
OriginRequestPolicyId (string) --
The unique identifier of the origin request policy that is attached to this cache behavior. For more information, see CreateOriginRequestPolicy.
ForwardedValues (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include values in the cache key, use a CachePolicy. See CreateCachePolicy.
If you want to send values to the origin but not include them in the cache key, use an OriginRequestPolicy. See CreateOriginRequestPolicy.
A complex type that specifies how CloudFront handles query strings, cookies, and HTTP headers.
QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.
Cookies (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.
Forward (string) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.
Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.
WhitelistedNames (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include cookies in the cache key, use CookiesConfig in a cache policy. See CreateCachePolicy.
If you want to send cookies to the origin but not include them in the cache key, use CookiesConfig in an origin request policy. See CreateOriginRequestPolicy.
Required if you specify whitelist for the value of Forward. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.
If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.
For the current limit on the number of cookie names that you can whitelist for each cache behavior, see CloudFront Limits in the AWS General Reference.
Quantity (integer) --
The number of cookie names in the Items list.
Items (list) --
A list of cookie names.
(string) --
Headers (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include headers in the cache key, use HeadersConfig in a cache policy. See CreateCachePolicy.
If you want to send headers to the origin but not include them in the cache key, use HeadersConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that specifies the Headers, if any, that you want CloudFront to forward to the origin for this cache behavior (whitelisted headers). For the headers that you specify, CloudFront also caches separate versions of a specified object that is based on the header values in viewer requests.
For more information, see Caching Content Based on Request Headers in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of header names in the Items list.
Items (list) --
A list of HTTP header names.
(string) --
QueryStringCacheKeys (dict) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use an QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
A complex type that contains information about the query string parameters that you want CloudFront to use for caching for this cache behavior.
Quantity (integer) --
The number of whitelisted query string parameters for a cache behavior.
Items (list) --
A list that contains the query string parameters that you want CloudFront to use as a basis for caching for a cache behavior. If Quantity is 0, you can omit Items.
(string) --
MinTTL (integer) --
This field is deprecated. We recommend that you use the MinTTL field in CachePolicyConfig instead of this field.
The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
You must specify 0 for MinTTL if you configure CloudFront to forward all headers to your origin (under Headers, if you specify 1 for Quantity and * for Name).
DefaultTTL (integer) --
This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
CustomErrorResponses (dict) --
A complex type that controls the following:
Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.
How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of HTTP status codes for which you want to specify a custom error page and/or a caching duration. If Quantity is 0, you can omit Items.
Items (list) --
A complex type that contains a CustomErrorResponse element for each HTTP status code for which you want to specify a custom error page and/or a caching duration.
(dict) --
A complex type that controls:
Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.
How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
ErrorCode (integer) --
The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) --
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) --
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) --
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) --
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) --
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) --
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
AliasICPRecordals (list) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
(dict) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can't configure it yourself.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
CNAME (string) --
A domain name associated with a distribution.
ICPRecordalStatus (string) --
The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.
The status values returned are the following:
APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.
SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.
PENDING indicates that CloudFront can't determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.
Location (string) --
The fully qualified URI of the new distribution resource just created.
ETag (string) --
The current version of the distribution created.

A complex type that lists the AWS accounts, if any, that you included in the TrustedSigners complex type for this distribution. These are the accounts that you want to allow to create signed URLs for private content.
The Signer complex type lists the AWS account number of the trusted signer or self if the signer is the AWS account that created the distribution. The Signer element also includes the IDs of any active CloudFront key pairs that are associated with the trusted signer's AWS account. If no KeyPairId element appears for a Signer, that signer can't create signed URLs.
For more information, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.

The date and time when the cache policy was last modified.
CachePolicyConfig (dict) --
The cache policy configuration.
Comment (string) --
A comment to describe the cache policy.
Name (string) --
A unique name to identify the cache policy.
DefaultTTL (integer) --
The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object’s time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.
MaxTTL (integer) --
The maximum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.
MinTTL (integer) --
The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
ParametersInCacheKeyAndForwardedToOrigin (dict) --
The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are automatically included in requests that CloudFront sends to the origin.
EnableAcceptEncodingGzip (boolean) --
A flag that determines whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
If this field is true and the viewer request includes the Accept-Encoding header, then CloudFront normalizes the value of the viewer’s Accept-Encoding header to one of the following:
Accept-Encoding: gzip (if gzip is in the viewer’s Accept-Encoding header)
Accept-Encoding: identity (if gzip is not in the viewer’s Accept-Encoding header)
CloudFront includes the normalized header in the cache key and includes it in requests that CloudFront sends to the origin.
If this field is false, then CloudFront treats the Accept-Encoding header the same as any other HTTP header in the viewer request. By default, it’s not included in the cache key and it’s not included in origin requests. You can manually add Accept-Encoding to the headers whitelist like any other HTTP header.
When this field is true, you should not whitelist the Accept-Encoding header in the cache policy or in an origin request policy attached to the same cache behavior.
For more information, see Cache compressed objects in the Amazon CloudFront Developer Guide.

all – All query strings in viewer requests are included in the cache key and are automatically included in requests that CloudFront sends to the origin.
QueryStrings (dict) --
Contains the specific query strings in viewer requests that either are or are not included in the cache key and automatically included in requests that CloudFront sends to the origin. The behavior depends on whether the QueryStringBehavior field in the CachePolicyQueryStringsConfig type is set to whitelist (the listed query strings are included) or allExcept (the listed query strings are not included, but all other query strings are).
Quantity (integer) --
The number of query string names in the Items list.

CachePolicy (dict) --
The cache policy.
Id (string) --
The unique identifier for the cache policy.
LastModifiedTime (datetime) --
The date and time when the cache policy was last modified.
CachePolicyConfig (dict) --
The cache policy configuration.
Comment (string) --
A comment to describe the cache policy.
Name (string) --
A unique name to identify the cache policy.
DefaultTTL (integer) --
The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object’s time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.
MaxTTL (integer) --
The maximum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.
MinTTL (integer) --
The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
ParametersInCacheKeyAndForwardedToOrigin (dict) --
The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are automatically included in requests that CloudFront sends to the origin.
EnableAcceptEncodingGzip (boolean) --
A flag that determines whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
If this field is true and the viewer request includes the Accept-Encoding header, then CloudFront normalizes the value of the viewer’s Accept-Encoding header to one of the following:
Accept-Encoding: gzip (if gzip is in the viewer’s Accept-Encoding header)
Accept-Encoding: identity (if gzip is not in the viewer’s Accept-Encoding header)
CloudFront includes the normalized header in the cache key and includes it in requests that CloudFront sends to the origin.
If this field is false, then CloudFront treats the Accept-Encoding header the same as any other HTTP header in the viewer request. By default, it’s not included in the cache key and it’s not included in origin requests. You can manually add Accept-Encoding to the headers whitelist like any other HTTP header.
When this field is true, you should not whitelist the Accept-Encoding header in the cache policy or in an origin request policy attached to the same cache behavior.
For more information, see Cache compressed objects in the Amazon CloudFront Developer Guide.

QueryStrings (dict) --
Contains the specific query strings in viewer requests that either are or are not included in the cache key and automatically included in requests that CloudFront sends to the origin. The behavior depends on whether the QueryStringBehavior field in the CachePolicyQueryStringsConfig type is set to whitelist (the listed query strings are included) or allExcept (the listed query strings are not included, but all other query strings are).
Quantity (integer) --
The number of query string names in the Items list.

Updates the configuration for a web distribution.
The update process includes getting the current distribution configuration, updating the XML document that is returned to make your changes, and then submitting an UpdateDistribution request to make the updates.
For information about updating a distribution using the CloudFront console instead, see Creating a Distribution in the Amazon CloudFront Developer Guide.
To update a web distribution using the CloudFront API
Submit a GetDistributionConfig request to get the current configuration and an Etag header for the distribution.
Update the XML document that was returned in the response to your GetDistributionConfig request to include your changes.
Submit an UpdateDistribution request to update the configuration for your distribution:
In the request body, include the XML document that you updated in Step 2. The request body must include an XML document with a DistributionConfig element.
Set the value of the HTTP If-Match header to the value of the ETag header that CloudFront returned when you submitted the GetDistributionConfig request in Step 1.
Review the response to the UpdateDistribution request to confirm that the configuration was successfully updated.
Optional: Submit a GetDistribution request to confirm that your changes have propagated. When propagation is complete, the value of Status is Deployed.

[REQUIRED]
The distribution's configuration information.
CallerReference (string) -- [REQUIRED]
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.
If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.
If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.
Aliases (dict) --

DefaultRootObject (string) --
The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution ( http://www.example.com) instead of an object in your distribution ( http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.
Specify only the object name, for example, index.html. Don't add a / before the object name.
If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.
To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.
To replace the default root object, update the distribution configuration and specify the new object.
For more information about the default root object, see Creating a Default Root Object in the Amazon CloudFront Developer Guide.
Origins (dict) -- [REQUIRED]
A complex type that contains information about origins for this distribution.
Quantity (integer) -- [REQUIRED]
The number of origins or origin groups for this distribution.
Items (list) -- [REQUIRED]
A complex type that contains origins or origin groups for this distribution.

For more information, see Adding Custom Headers to Origin Requests in the Amazon CloudFront Developer Guide.
Quantity (integer) -- [REQUIRED]
The number of custom headers, if any, for this distribution.
Items (list) --
Optional: A list that contains one OriginCustomHeader element for each custom header that you want CloudFront to forward to the origin. If Quantity is 0, omit Items.
(dict) --
A complex type that contains HeaderName and HeaderValue elements, if any, for this distribution.
HeaderName (string) -- [REQUIRED]
The name of a header that you want CloudFront to send to your origin. For more information, see Adding Custom Headers to Origin Requests in the Amazon CloudFront Developer Guide.
HeaderValue (string) -- [REQUIRED]
The value for the header that you specified in the HeaderName field.
S3OriginConfig (dict) --
Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting. To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.
OriginAccessIdentity (string) -- [REQUIRED]
The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:
origin-access-identity/cloudfront/ID-of-origin-access-identity
where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.
If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.
CustomOriginConfig (dict) --

Items (list) -- [REQUIRED]
A list that contains allowed SSL/TLS protocols for this distribution.
(string) --
OriginReadTimeout (integer) --
Specifies how long, in seconds, CloudFront waits for a response from the origin. This is also known as the origin response timeout. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 30 seconds.
For more information, see Origin Response Timeout in the Amazon CloudFront Developer Guide.
OriginKeepaliveTimeout (integer) --
Specifies how long, in seconds, CloudFront persists its connection to the origin. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 5 seconds.

If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.
Enabled (boolean) -- [REQUIRED]
Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.

allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) -- [REQUIRED]
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.

QueryString (boolean) -- [REQUIRED]
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated.

(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) -- [REQUIRED]
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) -- [REQUIRED]
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) -- [REQUIRED]
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.

ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) -- [REQUIRED]
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) -- [REQUIRED]
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) -- [REQUIRED]
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) -- [REQUIRED]
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) -- [REQUIRED]
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) -- [REQUIRED]
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) -- [REQUIRED]
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) -- [REQUIRED]
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) -- [REQUIRED]
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
string
[REQUIRED]
The distribution's id.
string
The value of the ETag header that you received when retrieving the distribution's configuration. For example: E2QWRUHAPOMQZL.

Distribution (dict) --
The distribution's information.
Id (string) --
The identifier for the distribution. For example: EDFDVBD632BHDS5.
ARN (string) --
The ARN (Amazon Resource Name) for the distribution. For example: arn:aws:cloudfront::123456789012:distribution/EDFDVBD632BHDS5, where 123456789012 is your AWS account ID.
Status (string) --
This response element indicates the current status of the distribution. When the status is Deployed, the distribution's information is fully propagated to all CloudFront edge locations.

InProgressInvalidationBatches (integer) --
The number of invalidation batches currently in progress.
DomainName (string) --
The domain name corresponding to the distribution, for example, d111111abcdef8.cloudfront.net.
ActiveTrustedSigners (dict) --
CloudFront automatically adds this element to the response only if you've set up the distribution to serve private content with signed URLs. The element lists the key pair IDs that CloudFront is aware of for each trusted signer. The Signer child element lists the AWS account number of the trusted signer (or an empty Self element if the signer is you). The Signer element also includes the IDs of any active key pairs associated with the trusted signer's AWS account. If no KeyPairId element appears for a Signer, that signer can't create working signed URLs.
Enabled (boolean) --
Enabled is true if any of the AWS accounts listed in the TrustedSigners complex type for this distribution have active CloudFront key pairs. If not, Enabled is false.
Quantity (integer) --
The number of trusted signers specified in the TrustedSigners complex type.
Items (list) --
A complex type that contains one Signer complex type for each trusted signer that is specified in the TrustedSigners complex type.

(string) --
DistributionConfig (dict) --
The current configuration information for the distribution. Send a GET request to the /CloudFront API version/distribution ID/config resource.
CallerReference (string) --
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.
If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.
If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.
Aliases (dict) --
A complex type that contains information about CNAMEs (alternate domain names), if any, for this distribution.
Quantity (integer) --
The number of CNAME aliases, if any, that you want to associate with this distribution.
Items (list) --
A complex type that contains the CNAME aliases, if any, that you want to associate with this distribution.

DefaultRootObject (string) --
The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution ( http://www.example.com) instead of an object in your distribution ( http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.
Specify only the object name, for example, index.html. Don't add a / before the object name.
If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.
To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.
To replace the default root object, update the distribution configuration and specify the new object.

The name of a header that you want CloudFront to send to your origin. For more information, see Adding Custom Headers to Origin Requests in the Amazon CloudFront Developer Guide.
HeaderValue (string) --
The value for the header that you specified in the HeaderName field.
S3OriginConfig (dict) --
Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting. To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.
OriginAccessIdentity (string) --
The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:
origin-access-identity/cloudfront/ID-of-origin-access-identity
where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.
If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.
CustomOriginConfig (dict) --
Use this type to specify an origin that is a content container or HTTP server, including an Amazon S3 bucket that is configured with static website hosting. To specify an Amazon S3 bucket that is not configured with static website hosting, use the S3OriginConfig type instead.

Specifies the protocol (HTTP or HTTPS) that CloudFront uses to connect to the origin. Valid values are:
http-only – CloudFront always uses HTTP to connect to the origin.
match-viewer – CloudFront connects to the origin using the same protocol that the viewer used to connect to CloudFront.
https-only – CloudFront always uses HTTPS to connect to the origin.
OriginSslProtocols (dict) --
Specifies the minimum SSL/TLS protocol that CloudFront uses when connecting to your origin over HTTPS. Valid values include SSLv3, TLSv1, TLSv1.1, and TLSv1.2.
For more information, see Minimum Origin SSL Protocol in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of SSL/TLS protocols that you want to allow CloudFront to use when establishing an HTTPS connection with this origin.
Items (list) --
A list that contains allowed SSL/TLS protocols for this distribution.
(string) --
OriginReadTimeout (integer) --
Specifies how long, in seconds, CloudFront waits for a response from the origin. This is also known as the origin response timeout. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 30 seconds.
For more information, see Origin Response Timeout in the Amazon CloudFront Developer Guide.
OriginKeepaliveTimeout (integer) --
Specifies how long, in seconds, CloudFront persists its connection to the origin. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 5 seconds.
For more information, see Origin Keep-alive Timeout in the Amazon CloudFront Developer Guide.
ConnectionAttempts (integer) --
The number of times that CloudFront attempts to connect to the origin. The minimum number is 1, the maximum is 3, and the default (if you don’t specify otherwise) is 3.
For a custom origin (including an Amazon S3 bucket that’s configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout.
For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide.
ConnectionTimeout (integer) --
The number of seconds that CloudFront waits when trying to establish a connection to the origin. The minimum timeout is 1 second, the maximum is 10 seconds, and the default (if you don’t specify otherwise) is 10 seconds.
For more information, see Origin Connection Timeout in the Amazon CloudFront Developer Guide.
OriginGroups (dict) --
A complex type that contains information about origin groups for this distribution.
Quantity (integer) --
The number of origin groups.
Items (list) --
The items (origin groups) in a distribution.
(dict) --
An origin group includes two origins (a primary origin and a second origin to failover to) and a failover criteria that you specify. You create an origin group to support origin failover in CloudFront. When you create or update a distribution, you can specifiy the origin group instead of a single origin, and CloudFront will failover from the primary origin to the second origin under the failover conditions that you've chosen.
Id (string) --
The origin group's ID.
FailoverCriteria (dict) --
A complex type that contains information about the failover criteria for an origin group.

TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.
TrustedSigners (dict) --
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.
Enabled (boolean) --
Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.

The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. You can specify the following options:
allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

EventType (string) --
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.

(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) --
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) --

The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) --
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) --
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) --
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) --
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) --
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) --
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
AliasICPRecordals (list) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
(dict) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can't configure it yourself.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
CNAME (string) --
A domain name associated with a distribution.
ICPRecordalStatus (string) --
The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.
The status values returned are the following:
APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.
SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.
PENDING indicates that CloudFront can't determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.
ETag (string) --
The current version of the configuration. For example: E2QWRUHAPOMQZL.
Deletes a cache policy.
You cannot delete a cache policy if it’s attached to a cache behavior. First update your distributions to remove the cache policy from all cache behaviors, then delete the cache policy.
To delete a cache policy, you must provide the policy’s identifier and version. To get these values, you can use ListCachePolicies or GetCachePolicy.
See also: AWS API Documentation
Request Syntax
client.delete_cache_policy(
Id='string',
IfMatch='string'
)
string
[REQUIRED]
The unique identifier for the cache policy that you are deleting. To get the identifier, you can use ListCachePolicies.
string
The version of the cache policy that you are deleting. The version is the cache policy’s ETag value, which you can get using ListCachePolicies, GetCachePolicy, or GetCachePolicyConfig.

S3OriginConfig (dict) --
Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting. To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.
OriginAccessIdentity (string) --
The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:
origin-access-identity/cloudfront/ID-of-origin-access-identity
where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.
If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.
CustomOriginConfig (dict) --
Use this type to specify an origin that is a content container or HTTP server, including an Amazon S3 bucket that is configured with static website hosting. To specify an Amazon S3 bucket that is not configured with static website hosting, use the S3OriginConfig type instead.

Items (list) --
A list that contains allowed SSL/TLS protocols for this distribution.
(string) --
OriginReadTimeout (integer) --
Specifies how long, in seconds, CloudFront waits for a response from the origin. This is also known as the origin response timeout. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 30 seconds.
For more information, see Origin Response Timeout in the Amazon CloudFront Developer Guide.
OriginKeepaliveTimeout (integer) --
Specifies how long, in seconds, CloudFront persists its connection to the origin. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 5 seconds.
For more information, see Origin Keep-alive Timeout in the Amazon CloudFront Developer Guide.
ConnectionAttempts (integer) --
The number of times that CloudFront attempts to connect to the origin. The minimum number is 1, the maximum is 3, and the default (if you don’t specify otherwise) is 3.
For a custom origin (including an Amazon S3 bucket that’s configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout.
For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide.
ConnectionTimeout (integer) --
The number of seconds that CloudFront waits when trying to establish a connection to the origin. The minimum timeout is 1 second, the maximum is 10 seconds, and the default (if you don’t specify otherwise) is 10 seconds.
For more information, see Origin Connection Timeout in the Amazon CloudFront Developer Guide.
OriginGroups (dict) --
A complex type that contains information about origin groups for this distribution.
Quantity (integer) --
The number of origin groups.
Items (list) --
The items (origin groups) in a distribution.
(dict) --
An origin group includes two origins (a primary origin and a second origin to failover to) and a failover criteria that you specify. You create an origin group to support origin failover in CloudFront. When you create or update a distribution, you can specifiy the origin group instead of a single origin, and CloudFront will failover from the primary origin to the second origin under the failover conditions that you've chosen.
Id (string) --
The origin group's ID.
FailoverCriteria (dict) --
A complex type that contains information about the failover criteria for an origin group.

OriginId (string) --
The ID for an origin in an origin group.
DefaultCacheBehavior (dict) --
A complex type that describes the default cache behavior if you don't specify a CacheBehavior element or if files don't match any of the values of PathPattern in CacheBehavior elements. You must create exactly one default cache behavior.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.
TrustedSigners (dict) --
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.
Enabled (boolean) --
Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.
Quantity (integer) --
The number of trusted signers for this cache behavior.
Items (list) --
Optional: A complex type that contains trusted signers for this cache behavior. If Quantity is 0, you can omit Items.
(string) --
ViewerProtocolPolicy (string) --
The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. You can specify the following options:
allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

A complex type that contains the HTTP methods that you want CloudFront to cache responses to.
(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

EventType (string) --
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.

QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) --
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) --

How long CloudFront caches HTTP status codes in the 4xx and 5xx range.
For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
ErrorCode (integer) --
The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.

If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:

Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
The Web ACL Id (if any) associated with the distribution.
HttpVersion (string) --
Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 will automatically use an earlier version.
IsIPV6Enabled (boolean) --
Whether CloudFront responds to IPv6 DNS requests with an IPv6 address for your distribution.
AliasICPRecordals (list) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
(dict) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can't configure it yourself.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
CNAME (string) --
A domain name associated with a distribution.
ICPRecordalStatus (string) --
The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.
The status values returned are the following:
APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.
SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.
PENDING indicates that CloudFront can't determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.
Gets an origin request policy, including the following metadata:
The policy’s identifier.
The date and time when the policy was last modified.
To get an origin request policy, you must provide the policy’s identifier. If the origin request policy is attached to a distribution’s cache behavior, you can get the policy’s identifier using ListDistributions or GetDistribution. If the origin request policy is not attached to a cache behavior, you can get the identifier using ListOriginRequestPolicies.

Creates a new RTMP distribution. An RTMP distribution is similar to a web distribution, but an RTMP distribution streams media files using the Adobe Real-Time Messaging Protocol (RTMP) instead of serving files using HTTP.
To create a new distribution, submit a POST request to the CloudFront API version/distribution resource. The request body must include a document with a StreamingDistributionConfig element. The response echoes the StreamingDistributionConfig element and returns other information about the RTMP distribution.
To get the status of your request, use the GET StreamingDistribution API action. When the value of Enabled is true and the value of Status is Deployed, your distribution is ready. A distribution usually deploys in less than 15 minutes.
For more information about web distributions, see Working with RTMP Distributions in the Amazon CloudFront Developer Guide.

(dict) --
CachePolicyConfig (dict) --
The cache policy configuration.
Comment (string) --
A comment to describe the cache policy.
Name (string) --
A unique name to identify the cache policy.
DefaultTTL (integer) --
The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object’s time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.
MaxTTL (integer) --
The maximum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.
MinTTL (integer) --
The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
ParametersInCacheKeyAndForwardedToOrigin (dict) --
The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are automatically included in requests that CloudFront sends to the origin.
EnableAcceptEncodingGzip (boolean) --
A flag that determines whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
If this field is true and the viewer request includes the Accept-Encoding header, then CloudFront normalizes the value of the viewer’s Accept-Encoding header to one of the following:
Accept-Encoding: gzip (if gzip is in the viewer’s Accept-Encoding header)
Accept-Encoding: identity (if gzip is not in the viewer’s Accept-Encoding header)
CloudFront includes the normalized header in the cache key and includes it in requests that CloudFront sends to the origin.
If this field is false, then CloudFront treats the Accept-Encoding header the same as any other HTTP header in the viewer request. By default, it’s not included in the cache key and it’s not included in origin requests. You can manually add Accept-Encoding to the headers whitelist like any other HTTP header.
When this field is true, you should not whitelist the Accept-Encoding header in the cache policy or in an origin request policy attached to the same cache behavior.
For more information, see Cache compressed objects in the Amazon CloudFront Developer Guide.

Creates an origin request policy.
After you create an origin request policy, you can attach it to one or more cache behaviors. When it’s attached to a cache behavior, the origin request policy determines the values that CloudFront includes in requests that it sends to the origin. Each request that CloudFront sends to the origin includes the following:
The request body and the URL path (without the domain name) from the viewer request.
The headers that CloudFront automatically includes in every origin request, including Host, User-Agent, and X-Amz-Cf-Id.
All HTTP headers, cookies, and URL query strings that are specified in the cache policy or the origin request policy. These can include items from the viewer request and, in the case of headers, additional ones that are added by CloudFront.
CloudFront sends a request when it can’t find a valid object in its cache that matches the request. If you want to send values to the origin and also include them in the cache key, use CreateCachePolicy.
For more information about origin request policies, see Controlling origin requests in the Amazon CloudFront Developer Guide.

The distribution's configuration information.
DistributionConfig (dict) -- [REQUIRED]
A distribution configuration.
CallerReference (string) -- [REQUIRED]
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.
If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.
If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.
Aliases (dict) --

Quantity (integer) -- [REQUIRED]
The number of CNAME aliases, if any, that you want to associate with this distribution.
Items (list) --
A complex type that contains the CNAME aliases, if any, that you want to associate with this distribution.
(string) --
DefaultRootObject (string) --
The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution ( http://www.example.com) instead of an object in your distribution ( http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.
Specify only the object name, for example, index.html. Don't add a / before the object name.
If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.
To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.
To replace the default root object, update the distribution configuration and specify the new object.
For more information about the default root object, see Creating a Default Root Object in the Amazon CloudFront Developer Guide.
Origins (dict) -- [REQUIRED]
A complex type that contains information about origins for this distribution.
Quantity (integer) -- [REQUIRED]
The number of origins or origin groups for this distribution.
Items (list) -- [REQUIRED]
A complex type that contains origins or origin groups for this distribution.

Use the CustomOriginConfig type to specify various other kinds of content containers or HTTP servers, including:
An Amazon S3 bucket that is configured with static website hosting
An Elastic Load Balancing load balancer
An AWS Elemental MediaPackage origin
An AWS Elemental MediaStore container
Any other HTTP server, running on an Amazon EC2 instance or any other kind of host
For the current maximum number of origins that you can specify per distribution, see General Quotas on Web Distributions in the Amazon CloudFront Developer Guide (quotas were formerly referred to as limits).

HeaderValue (string) -- [REQUIRED]
The value for the header that you specified in the HeaderName field.
S3OriginConfig (dict) --
Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting. To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.
OriginAccessIdentity (string) -- [REQUIRED]
The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:
origin-access-identity/cloudfront/ID-of-origin-access-identity
where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.
If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.
CustomOriginConfig (dict) --
Use this type to specify an origin that is a content container or HTTP server, including an Amazon S3 bucket that is configured with static website hosting. To specify an Amazon S3 bucket that is not configured with static website hosting, use the S3OriginConfig type instead.

match-viewer – CloudFront connects to the origin using the same protocol that the viewer used to connect to CloudFront.
https-only – CloudFront always uses HTTPS to connect to the origin.
OriginSslProtocols (dict) --
Specifies the minimum SSL/TLS protocol that CloudFront uses when connecting to your origin over HTTPS. Valid values include SSLv3, TLSv1, TLSv1.1, and TLSv1.2.
For more information, see Minimum Origin SSL Protocol in the Amazon CloudFront Developer Guide.
Quantity (integer) -- [REQUIRED]
The number of SSL/TLS protocols that you want to allow CloudFront to use when establishing an HTTPS connection with this origin.
Items (list) -- [REQUIRED]
A list that contains allowed SSL/TLS protocols for this distribution.
(string) --
OriginReadTimeout (integer) --
Specifies how long, in seconds, CloudFront waits for a response from the origin. This is also known as the origin response timeout. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 30 seconds.
For more information, see Origin Response Timeout in the Amazon CloudFront Developer Guide.
OriginKeepaliveTimeout (integer) --
Specifies how long, in seconds, CloudFront persists its connection to the origin. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 5 seconds.
For more information, see Origin Keep-alive Timeout in the Amazon CloudFront Developer Guide.
ConnectionAttempts (integer) --
The number of times that CloudFront attempts to connect to the origin. The minimum number is 1, the maximum is 3, and the default (if you don’t specify otherwise) is 3.
For a custom origin (including an Amazon S3 bucket that’s configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout.
For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide.
ConnectionTimeout (integer) --
The number of seconds that CloudFront waits when trying to establish a connection to the origin. The minimum timeout is 1 second, the maximum is 10 seconds, and the default (if you don’t specify otherwise) is 10 seconds.
For more information, see Origin Connection Timeout in the Amazon CloudFront Developer Guide.
OriginGroups (dict) --
A complex type that contains information about origin groups for this distribution.
Quantity (integer) -- [REQUIRED]

TargetOriginId (string) -- [REQUIRED]
The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.
TrustedSigners (dict) -- [REQUIRED]
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.

EventType (string) -- [REQUIRED]
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.

This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated.

(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) -- [REQUIRED]
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) -- [REQUIRED]
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) -- [REQUIRED]
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.

The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. You can specify the following options:
allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --

The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) -- [REQUIRED]
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) -- [REQUIRED]
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) -- [REQUIRED]
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) -- [REQUIRED]
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) -- [REQUIRED]
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) -- [REQUIRED]
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) -- [REQUIRED]
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) -- [REQUIRED]
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) -- [REQUIRED]
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
Tags (dict) -- [REQUIRED]
A complex type that contains zero or more Tag elements.
Items (list) --
A complex type that contains Tag elements.
(dict) --
A complex type that contains Tag key and Tag value.
Key (string) -- [REQUIRED]
A string that contains Tag key.
The string length should be between 1 and 128 characters. Valid characters include a-z, A-Z, 0-9, space, and the special characters _ - . : / = + @.
Value (string) --
A string that contains an optional Tag value.
The string length should be between 0 and 256 characters. Valid characters include a-z, A-Z, 0-9, space, and the special characters _ - . : / = + @.

Distribution (dict) --
The distribution's information.
Id (string) --
The identifier for the distribution. For example: EDFDVBD632BHDS5.
ARN (string) --
The ARN (Amazon Resource Name) for the distribution. For example: arn:aws:cloudfront::123456789012:distribution/EDFDVBD632BHDS5, where 123456789012 is your AWS account ID.
Status (string) --
This response element indicates the current status of the distribution. When the status is Deployed, the distribution's information is fully propagated to all CloudFront edge locations.

The number of invalidation batches currently in progress.
DomainName (string) --
The domain name corresponding to the distribution, for example, d111111abcdef8.cloudfront.net.
ActiveTrustedSigners (dict) --
CloudFront automatically adds this element to the response only if you've set up the distribution to serve private content with signed URLs. The element lists the key pair IDs that CloudFront is aware of for each trusted signer. The Signer child element lists the AWS account number of the trusted signer (or an empty Self element if the signer is you). The Signer element also includes the IDs of any active key pairs associated with the trusted signer's AWS account. If no KeyPairId element appears for a Signer, that signer can't create working signed URLs.
Enabled (boolean) --
Enabled is true if any of the AWS accounts listed in the TrustedSigners complex type for this distribution have active CloudFront key pairs. If not, Enabled is false.
Quantity (integer) --
The number of trusted signers specified in the TrustedSigners complex type.
Items (list) --
A complex type that contains one Signer complex type for each trusted signer that is specified in the TrustedSigners complex type.

(string) --
DistributionConfig (dict) --
The current configuration information for the distribution. Send a GET request to the /CloudFront API version/distribution ID/config resource.
CallerReference (string) --
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.
If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.
If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.
Aliases (dict) --
A complex type that contains information about CNAMEs (alternate domain names), if any, for this distribution.
Quantity (integer) --
The number of CNAME aliases, if any, that you want to associate with this distribution.
Items (list) --
A complex type that contains the CNAME aliases, if any, that you want to associate with this distribution.
(string) --
DefaultRootObject (string) --
The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution ( http://www.example.com) instead of an object in your distribution ( http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.
Specify only the object name, for example, index.html. Don't add a / before the object name.
If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.
To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.
To replace the default root object, update the distribution configuration and specify the new object.

The name of a header that you want CloudFront to send to your origin. For more information, see Adding Custom Headers to Origin Requests in the Amazon CloudFront Developer Guide.
HeaderValue (string) --
The value for the header that you specified in the HeaderName field.
S3OriginConfig (dict) --
Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting. To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.
OriginAccessIdentity (string) --
The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:
origin-access-identity/cloudfront/ID-of-origin-access-identity
where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.
If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.
To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.
To replace the origin access identity, update the distribution configuration and specify the new origin access identity.
For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.
CustomOriginConfig (dict) --
Use this type to specify an origin that is a content container or HTTP server, including an Amazon S3 bucket that is configured with static website hosting. To specify an Amazon S3 bucket that is not configured with static website hosting, use the S3OriginConfig type instead.

https-only – CloudFront always uses HTTPS to connect to the origin.
OriginSslProtocols (dict) --
Specifies the minimum SSL/TLS protocol that CloudFront uses when connecting to your origin over HTTPS. Valid values include SSLv3, TLSv1, TLSv1.1, and TLSv1.2.
For more information, see Minimum Origin SSL Protocol in the Amazon CloudFront Developer Guide.
Quantity (integer) --
The number of SSL/TLS protocols that you want to allow CloudFront to use when establishing an HTTPS connection with this origin.
Items (list) --
A list that contains allowed SSL/TLS protocols for this distribution.
(string) --
OriginReadTimeout (integer) --
Specifies how long, in seconds, CloudFront waits for a response from the origin. This is also known as the origin response timeout. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 30 seconds.
For more information, see Origin Response Timeout in the Amazon CloudFront Developer Guide.
OriginKeepaliveTimeout (integer) --
Specifies how long, in seconds, CloudFront persists its connection to the origin. The minimum timeout is 1 second, the maximum is 60 seconds, and the default (if you don’t specify otherwise) is 5 seconds.
For more information, see Origin Keep-alive Timeout in the Amazon CloudFront Developer Guide.
ConnectionAttempts (integer) --
The number of times that CloudFront attempts to connect to the origin. The minimum number is 1, the maximum is 3, and the default (if you don’t specify otherwise) is 3.
For a custom origin (including an Amazon S3 bucket that’s configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout.
For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide.
ConnectionTimeout (integer) --
The number of seconds that CloudFront waits when trying to establish a connection to the origin. The minimum timeout is 1 second, the maximum is 10 seconds, and the default (if you don’t specify otherwise) is 10 seconds.
For more information, see Origin Connection Timeout in the Amazon CloudFront Developer Guide.
OriginGroups (dict) --
A complex type that contains information about origin groups for this distribution.
Quantity (integer) --
The number of origin groups.
Items (list) --
The items (origin groups) in a distribution.
(dict) --
An origin group includes two origins (a primary origin and a second origin to failover to) and a failover criteria that you specify. You create an origin group to support origin failover in CloudFront. When you create or update a distribution, you can specifiy the origin group instead of a single origin, and CloudFront will failover from the primary origin to the second origin under the failover conditions that you've chosen.
Id (string) --
The origin group's ID.
FailoverCriteria (dict) --
A complex type that contains information about the failover criteria for an origin group.

DefaultCacheBehavior (dict) --
A complex type that describes the default cache behavior if you don't specify a CacheBehavior element or if files don't match any of the values of PathPattern in CacheBehavior elements. You must create exactly one default cache behavior.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they use the default cache behavior.
TrustedSigners (dict) --
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the PathPattern for this cache behavior, specify true for Enabled, and specify the applicable values for Quantity and Items. For more information, see Serving Private Content with Signed URLs and Signed Cookies in the Amazon CloudFront Developer Guide.
If you don’t want to require signed URLs in requests for objects that match PathPattern, specify false for Enabled and 0 for Quantity. Omit Items.
To add, change, or remove one or more trusted signers, change Enabled to true (if it’s currently false), change Quantity as applicable, and specify all of the trusted signers that you want to include in the updated distribution.
Enabled (boolean) --
Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.
Quantity (integer) --
The number of trusted signers for this cache behavior.
Items (list) --
Optional: A complex type that contains trusted signers for this cache behavior. If Quantity is 0, you can omit Items.
(string) --
ViewerProtocolPolicy (string) --
The protocol that viewers can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. You can specify the following options:
allow-all: Viewers can use HTTP or HTTPS.
redirect-to-https: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
https-only: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see Requiring HTTPS Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
AllowedMethods (dict) --
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
CloudFront forwards only GET and HEAD requests.
CloudFront forwards only GET, HEAD, and OPTIONS requests.
CloudFront forwards GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can't perform operations that you don't want them to. For example, you might not want users to have permissions to delete objects from your origin.
Quantity (integer) --
The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

A complex type that contains the HTTP methods that you want CloudFront to cache responses to.
(string) --
SmoothStreaming (boolean) --
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false. If you specify true for SmoothStreaming, you can still distribute other content using this cache behavior if the content matches the value of PathPattern.
Compress (boolean) --
Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

LambdaFunctionARN (string) --
The ARN of the Lambda function. You must specify the ARN of a function version; you can't specify a Lambda alias or $LATEST.
EventType (string) --
Specifies the event type that triggers a Lambda function invocation. You can specify the following values:
viewer-request: The function executes when CloudFront receives a request from a viewer and before it checks to see whether the requested object is in the edge cache.
origin-request: The function executes only when CloudFront sends a request to your origin. When the requested object is in the edge cache, the function doesn't execute.
origin-response: The function executes after CloudFront receives a response from the origin and before it caches the object in the response. When the requested object is in the edge cache, the function doesn't execute.
viewer-response: The function executes before CloudFront returns the requested object to the viewer. The function executes regardless of whether the object was already in the edge cache. If the origin returns an HTTP status code other than HTTP 200 (OK), the function doesn't execute.

QueryString (boolean) --
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field.
If you want to include query strings in the cache key, use QueryStringsConfig in a cache policy. See CreateCachePolicy.
If you want to send query strings to the origin but not include them in the cache key, use QueryStringsConfig in an origin request policy. See CreateOriginRequestPolicy.
Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:
If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.
If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.
If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.
For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

This field is deprecated. We recommend that you use the DefaultTTL field in CachePolicyConfig instead of this field.
The default amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin does not add HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
MaxTTL (integer) --
This field is deprecated. We recommend that you use the MaxTTL field in CachePolicyConfig instead of this field.
The maximum amount of time that you want objects to stay in CloudFront caches before CloudFront forwards another request to your origin to determine whether the object has been updated. The value that you specify applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.

(dict) --
A complex type that describes how CloudFront processes requests.
You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.
For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see Quotas in the Amazon CloudFront Developer Guide.
If you don’t want to specify any cache behaviors, include only an empty CacheBehaviors element. Don’t include an empty CacheBehavior element because this is invalid.
To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty CacheBehaviors element.
To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.
For more information about cache behaviors, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.
PathPattern (string) --
The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.
The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.
For more information, see Path Pattern in the Amazon CloudFront Developer Guide.
TargetOriginId (string) --
The value of ID for the origin that you want CloudFront to route requests to when they match this cache behavior.
TrustedSigners (dict) --

For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
ErrorCode (integer) --
The HTTP status code for which you want to specify a custom error page and/or a caching duration.
ResponsePagePath (string) --
The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:
The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.
The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.
If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.
We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
ResponseCode (string) --
The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:
Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.
If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.
You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.
If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.
ErrorCachingMinTTL (integer) --
The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.
For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.
Comment (string) --
Any comments you want to include about the distribution.
If you don't want to specify a comment, include an empty Comment element.
To delete an existing comment, update the distribution configuration and include an empty Comment element.
To add or change a comment, update the distribution configuration and specify the new comment.
Logging (dict) --
A complex type that controls whether access logs are written for the distribution.
For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.
Enabled (boolean) --
Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you don't want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.
IncludeCookies (boolean) --
Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you don't want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.
Bucket (string) --
The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.
Prefix (string) --
An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you don't want to specify a prefix, you still must include an empty Prefix element in the Logging element.
PriceClass (string) --
The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.
If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.
For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes (such as Price Class 100) map to CloudFront regions, see Amazon CloudFront Pricing. For price class information, scroll down to see the table at the bottom of the page.
Enabled (boolean) --
From this field, you can enable or disable the selected distribution.
ViewerCertificate (dict) --
A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.
CloudFrontDefaultCertificate (boolean) --
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.
If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:
ACMCertificateArn or IAMCertificateId (specify a value for one, not both)
MinimumProtocolVersion
SSLSupportMethod
IAMCertificateId (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Identity and Access Management (AWS IAM), provide the ID of the IAM certificate.
If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
ACMCertificateArn (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in AWS Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region ( us-east-1).
If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVerison and SSLSupportMethod.
SSLSupportMethod (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.
sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.
vip – The distribution accepts HTTPS connections from all viewers including those that don’t support SNI. This is not recommended, and results in additional monthly charges from CloudFront.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don’t set a value for this field.
MinimumProtocolVersion (string) --
If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:
The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.
The ciphers that CloudFront can use to encrypt the content that it returns to viewers.
For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.
When you’re using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.
If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.
Certificate (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
CertificateSource (string) --
This field is deprecated. Use one of the following fields instead:
ACMCertificateArn
IAMCertificateId
CloudFrontDefaultCertificate
Restrictions (dict) --
A complex type that identifies ways in which you want to restrict distribution of your content.
GeoRestriction (dict) --
A complex type that controls the countries in which your content is distributed. CloudFront determines the location of your users using MaxMind GeoIP databases.
RestrictionType (string) --
The method that you want to use to restrict distribution of your content by country:
none: No geo restriction is enabled, meaning access to content is not restricted by client geo location.
blacklist: The Location elements specify the countries in which you don't want CloudFront to distribute your content.
whitelist: The Location elements specify the countries in which you want CloudFront to distribute your content.
Quantity (integer) --
When geo restriction is enabled, this is the number of countries in your whitelist or blacklist. Otherwise, when it is not enabled, Quantity is 0, and you can omit Items.
Items (list) --
A complex type that contains a Location element for each country in which you want CloudFront either to distribute your content ( whitelist) or not distribute your content ( blacklist).
The Location element is a two-letter, uppercase country code for a country that you want to include in your blacklist or whitelist. Include one Location element for each country.
CloudFront and MaxMind both use ISO 3166 country codes. For the current list of countries and the corresponding codes, see ISO 3166-1-alpha-2 code on the International Organization for Standardization website. You can also refer to the country list on the CloudFront console, which includes both country names and codes.
(string) --
WebACLId (string) --
A unique identifier that specifies the AWS WAF web ACL, if any, to associate with this distribution. To specify a web ACL created using the latest version of AWS WAF, use the ACL ARN, for example arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/473e64fd-f30b-4765-81a0-62ad96dd167a. To specify a web ACL created using AWS WAF Classic, use the ACL ID, for example 473e64fd-f30b-4765-81a0-62ad96dd167a.
AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to CloudFront, and lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, CloudFront responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You can also configure CloudFront to return a custom error page when a request is blocked. For more information about AWS WAF, see the AWS WAF Developer Guide.
HttpVersion (string) --
(Optional) Specify the maximum HTTP version that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.
For viewers and CloudFront to use HTTP/2, viewers must support TLS 1.2 or later, and must support Server Name Identification (SNI).
In general, configuring CloudFront to communicate with viewers using HTTP/2 reduces latency. You can improve performance by optimizing for HTTP/2. For more information, do an Internet search for "http/2 optimization."
IsIPV6Enabled (boolean) --
If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.
In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.
If you're using an Amazon Route 53 alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:
You enable IPv6 for the distribution
You're using alternate domain names in the URLs for your objects
For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Amazon Route 53 Developer Guide.
If you created a CNAME resource record set, either with Amazon Route 53 or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.
AliasICPRecordals (list) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
(dict) --
AWS services in China customers must file for an Internet Content Provider (ICP) recordal if they want to serve content publicly on an alternate domain name, also known as a CNAME, that they've added to CloudFront. AliasICPRecordal provides the ICP recordal status for CNAMEs associated with distributions. The status is returned in the CloudFront response; you can't configure it yourself.
For more information about ICP recordals, see Signup, Accounts, and Credentials in Getting Started with AWS services in China.
CNAME (string) --
A domain name associated with a distribution.
ICPRecordalStatus (string) --
The Internet Content Provider (ICP) recordal status for a CNAME. The ICPRecordalStatus is set to APPROVED for all CNAMEs (aliases) in regions outside of China.
The status values returned are the following:
APPROVED indicates that the associated CNAME has a valid ICP recordal number. Multiple CNAMEs can be associated with a distribution, and CNAMEs can correspond to different ICP recordals. To be marked as APPROVED, that is, valid to use with China region, a CNAME must have one ICP recordal number associated with it.
SUSPENDED indicates that the associated CNAME does not have a valid ICP recordal number.
PENDING indicates that CloudFront can't determine the ICP recordal status of the CNAME associated with the distribution because there was an error in trying to determine the status. You can try again to see if the error is resolved in which case CloudFront returns an APPROVED or SUSPENDED status.
Location (string) --
The fully qualified URI of the new distribution resource just created.
ETag (string) --
The current version of the distribution created.

A unique name to identify the cache policy.
DefaultTTL (integer) --
The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object’s time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.
MaxTTL (integer) --
The maximum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.
MinTTL (integer) -- [REQUIRED]
The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.
ParametersInCacheKeyAndForwardedToOrigin (dict) --
The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are automatically included in requests that CloudFront sends to the origin.
EnableAcceptEncodingGzip (boolean) -- [REQUIRED]
A flag that determines whether the Accept-Encoding HTTP header is included in the cache key and included in requests that CloudFront sends to the origin.
If this field is true and the viewer request includes the Accept-Encoding header, then CloudFront normalizes the value of the viewer’s Accept-Encoding header to one of the following:
Accept-Encoding: gzip (if gzip is in the viewer’s Accept-Encoding header)
Accept-Encoding: identity (if gzip is not in the viewer’s Accept-Encoding header)
CloudFront includes the normalized header in the cache key and includes it in requests that CloudFront sends to the origin.
If this field is false, then CloudFront treats the Accept-Encoding header the same as any other HTTP header in the viewer request. By default, it’s not included in the cache key and it’s not included in origin requests. You can manually add Accept-Encoding to the headers whitelist like any other HTTP header.
When this field is true, you should not whitelist the Accept-Encoding header in the cache policy or in an origin request policy attached to the same cache behavior.

Deletes an origin request policy.
You cannot delete an origin request policy if it’s attached to any cache behaviors. First update your distributions to remove the origin request policy from all cache behaviors, then delete the origin request policy.
To delete an origin request policy, you must provide the policy’s identifier and version. To get the identifier, you can use ListOriginRequestPolicies or GetOriginRequestPolicy.
