-- | A cache policy.
--
-- 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 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@.
--
-- /See:/ 'newCachePolicy' smart constructor.
