Warning
We recommend using
TrustedKeyGroupsinstead ofTrustedSigners.A list of Amazon Web Services account IDs whose public keys CloudFront can use to validate signed URLs or signed cookies.
When a cache behavior contains trusted signers, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with the private key of a CloudFront key pair in a trusted signer’s Amazon Web Services account. The signed URL or cookie contains information about which public key CloudFront should use to verify the signature. For more information, see Serving private content in the Amazon CloudFront Developer Guide.
Enabled (boolean) –
This field is
trueif any of the Amazon Web Services accounts in the list are configured as trusted signers. If not, this field isfalse.Quantity (integer) –
The number of Amazon Web Services accounts in the list.
Items (list) –
A list of Amazon Web Services account identifiers.
(string) –
TrustedKeyGroups (dict) –
A list of key groups that CloudFront can use to validate signed URLs or signed cookies.
When a cache behavior contains trusted key groups, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with a private key whose corresponding public key is in the key group. The signed URL or cookie contains information about which public key CloudFront should use to verify the signature. For more information, see Serving private content in the Amazon CloudFront Developer Guide.
Enabled (boolean) –
This field is
trueif any of the key groups in the list have public keys that CloudFront can use to verify the signatures of signed URLs and signed cookies. If not, this field isfalse.Quantity (integer) –
The number of key groups in the list.
Items (list) –
A list of key groups identifiers.
(string) –
ViewerProtocolPolicy (string) –
The protocol that viewers can use to access the files in the origin specified by
TargetOriginIdwhen a request matches the path pattern inPathPattern. 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.
Note
The only way to guarantee that viewers retrieve an object that was fetched from the origin using HTTPS is never to use any other protocol to fetch the object. If you have recently changed from HTTP to HTTPS, we recommend that you clear your objects’ cache because cached objects are protocol agnostic. That means that an edge location will return an object from the cache regardless of whether the current request protocol matches the protocol used previously. For more information, see Managing Cache Expiration 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
GETandHEADrequests.CloudFront forwards only
GET,HEAD, andOPTIONSrequests.CloudFront forwards
GET, HEAD, OPTIONS, PUT, PATCH, POST, andDELETErequests.
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
GETandHEADrequests), 3 (forGET,HEAD, andOPTIONSrequests) and 7 (forGET, HEAD, OPTIONS, PUT, PATCH, POST, andDELETErequests).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
GETandHEADrequests.CloudFront caches responses to
GET,HEAD, andOPTIONSrequests.
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 toGETandHEADrequests) and3(for caching responses toGET,HEAD, andOPTIONSrequests).Items (list) –

Specifies the event type that triggers a Lambda@Edge 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@Edge 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.

The gRPC configuration for your cache behavior.
Enabled (boolean) –
Enables your CloudFront distribution to receive gRPC requests and to proxy them directly to your origins.
ForwardedValues (dict) –
This field is deprecated. We recommend that you use a cache policy or an origin request policy instead of this field. For more information, see Working with policies in the Amazon CloudFront Developer Guide.
If you want to include values in the cache key, use a cache policy. For more information, see Creating cache policies or Using the managed cache policies in the Amazon CloudFront Developer Guide.
If you want to send values to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies or Using the managed origin request policies in the Amazon CloudFront Developer Guide.

DefaultCacheBehaviormust include either aCachePolicyIdorForwardedValues. We recommend that you use aCachePolicyId.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 a cache policy. For more information, see Creating cache policies in the Amazon CloudFront Developer Guide.
If you want to send query strings to the origin but not include them in the cache key, use an origin request policy. For more information, see Creating origin request policies in the Amazon CloudFront Developer Guide.
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
QueryStringand on the values that you specify forQueryStringCacheKeys, if any:If you specify true for
QueryStringand you don’t specify any values forQueryStringCacheKeys, 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
QueryStringand you specify one or more values forQueryStringCacheKeys, 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) –

CacheBehaviorelements.Quantity (integer) –
The number of cache behaviors for this distribution.
Items (list) –
Optional: A complex type that contains cache behaviors for this distribution. If
Quantityis0, you can omitItems.(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
CacheBehaviorselement. Don’t specify an empty individualCacheBehaviorelement, because this is invalid. For more information, see CacheBehaviors.To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty
CacheBehaviorselement.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.Note
You can optionally include a slash (
/) at the beginning of the path pattern. For example,/images/*.jpg. CloudFront behavior is the same with or without the leading/.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.

IDfor the origin that you want CloudFront to route requests to when they match this cache behavior.TrustedSigners (dict) –
Warning
We recommend using
TrustedKeyGroupsinstead ofTrustedSigners.A list of Amazon Web Services account IDs whose public keys CloudFront can use to validate signed URLs or signed cookies.
When a cache behavior contains trusted signers, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with the private key of a CloudFront key pair in the trusted signer’s Amazon Web Services account. The signed URL or cookie contains information about which public key CloudFront should use to verify the signature. For more information, see Serving private content in the Amazon CloudFront Developer Guide.
Enabled (boolean) –
This field is
trueif any of the Amazon Web Services accounts in the list are configured as trusted signers. If not, this field isfalse.Quantity (integer) –

When a cache behavior contains trusted key groups, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior. The URLs or cookies must be signed with a private key whose corresponding public key is in the key group. The signed URL or cookie contains information about which public key CloudFront should use to verify the signature. For more information, see Serving private content in the Amazon CloudFront Developer Guide.
Enabled (boolean) –
This field is
trueif any of the key groups in the list have public keys that CloudFront can use to verify the signatures of signed URLs and signed cookies. If not, this field isfalse.Quantity (integer) –

Items (list) –
A list of key groups identifiers.
(string) –
ViewerProtocolPolicy (string) –
The protocol that viewers can use to access the files in the origin specified by
TargetOriginIdwhen a request matches the path pattern inPathPattern. 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.
Note
The only way to guarantee that viewers retrieve an object that was fetched from the origin using HTTPS is never to use any other protocol to fetch the object. If you have recently changed from HTTP to HTTPS, we recommend that you clear your objects’ cache because cached objects are protocol agnostic. That means that an edge location will return an object from the cache regardless of whether the current request protocol matches the protocol used previously. For more information, see Managing Cache Expiration in the Amazon CloudFront Developer Guide.

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
QueryStringand on the values that you specify forQueryStringCacheKeys, if any:If you specify true for
QueryStringand you don’t specify any values forQueryStringCacheKeys, 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
QueryStringand you specify one or more values forQueryStringCacheKeys, 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.

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
PathPatternmatches 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
TargetOriginIdspecifies the value of theIDelement for the origin that contains your custom error pages.
If you specify a value for
ResponsePagePath, you must also specify a value forResponseCode.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
400or500as theResponseCodefor all 4xx or 5xx errors.You might want to return a
200status 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 forResponsePagePath.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.
