-- | A complex type that controls which HTTP methods CloudFront processes and
-- forwards to your Amazon S3 bucket or your custom origin. There are three
-- choices:
--
-- -   CloudFront forwards only @GET@ and @HEAD@ requests.
--
-- -   CloudFront forwards only @GET@, @HEAD@, and @OPTIONS@ requests.
--
-- -   CloudFront forwards @GET, HEAD, OPTIONS, PUT, PATCH, POST@, and
--     @DELETE@ requests.
--
-- If you pick the third choice, you may need to restrict access to your
-- Amazon S3 bucket or to your custom origin so users can\'t perform
-- operations that you don\'t want them to. For example, you might not want
-- users to have permissions to delete objects from your origin.
--
-- /See:/ 'newAllowedMethods' smart constructor.
