CachePolicyQueryStringsConfig

An object that determines whether any URL query strings in viewer requests (and if so, which query strings) are included in the cache key and in requests that CloudFront sends to the origin.

QueryStringBehavior

Determines whether any URL query strings in viewer requests are included in the cache key and in requests that CloudFront sends to the origin. Valid values are:

none – No query strings in viewer requests are included in the cache key or in requests that CloudFront sends to the origin. Even when this field is set to none, any query strings that are listed in an OriginRequestPolicy are included in origin requests.
whitelist – Only the query strings in viewer requests that are listed in the QueryStringNames type are included in the cache key and in requests that CloudFront sends to the origin.
allExcept – All query strings in viewer requests are included in the cache key and in requests that CloudFront sends to the origin, except those that are listed in the QueryStringNames type, which are not included.
all – All query strings in viewer requests are included in the cache key and in requests that CloudFront sends to the origin.

Type: String

Valid Values: none | whitelist | allExcept | all

Required: Yes

QueryStrings

Contains the specific query strings in viewer requests that either are or are not included in the cache key and 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).

Type: QueryStringNames object

Required: No
