Expand description
A cache policy configuration.
This configuration 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 a valid 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 OriginRequestPolicy
.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.comment: Option<String>
A comment to describe the cache policy. The comment cannot be longer than 128 characters.
name: Option<String>
A unique name to identify the cache policy.
default_ttl: Option<i64>
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
.
max_ttl: Option<i64>
The maximum amount of time, in seconds, that objects 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
.
min_ttl: Option<i64>
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.
parameters_in_cache_key_and_forwarded_to_origin: Option<ParametersInCacheKeyAndForwardedToOrigin>
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.
Implementations
A comment to describe the cache policy. The comment cannot be longer than 128 characters.
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

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
.
The maximum amount of time, in seconds, that objects 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

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.
