-- | A complex type that controls whether CloudFront caches the response to
-- requests using the specified HTTP methods. There are two choices:
--
-- -   CloudFront caches responses to @GET@ and @HEAD@ requests.
--
-- -   CloudFront caches responses to @GET@, @HEAD@, and @OPTIONS@
--     requests.
--
-- If you pick the second choice for your Amazon S3 Origin, you may need to
-- forward Access-Control-Request-Method, Access-Control-Request-Headers,
-- and Origin headers for the responses to be cached correctly.
