-- 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
-- @OriginRequestPolicy@.
--
-- For more information about cache policies, see
-- <https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/controlling-the-cache-key.html Controlling the cache key>
-- in the /Amazon CloudFront Developer Guide/.
