@Generated(value="software.amazon.awssdk:codegen") public final class CachePolicyConfig extends Object implements SdkPojo, Serializable, ToCopyableBuilder<CachePolicyConfig.Builder,CachePolicyConfig>
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
.

public final Long defaultTTL()
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
.

The default value for this field is 86400 seconds (one day). If the value of MinTTL

public final Long maxTTL()
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

The default value for this field is 31536000 seconds (one year). If the value of MinTTL
or

is more than 31536000 seconds, then the default value for this field is the same as the
value of DefaultTTL
