// 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
// also 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 OriginRequestPolicy . 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.
