-- Gets a response headers policy configuration.
--
-- To get a response headers policy configuration, you must provide the
-- policy\'s identifier. If the response headers policy is attached to a
-- distribution\'s cache behavior, you can get the policy\'s identifier
-- using @ListDistributions@ or @GetDistribution@. If the response headers
-- policy is not attached to a cache behavior, you can get the identifier
-- using @ListResponseHeadersPolicies@.
