// CreateCachePolicyRequest returns a request value for making API operation for
// Amazon CloudFront.
//
// 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
// (https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/controlling-the-cache-key.html)
// in the Amazon CloudFront Developer Guide.
