-- Deletes a cache policy.
--
-- You cannot delete a cache policy if it\'s attached to a cache behavior.
-- First update your distributions to remove the cache policy from all
-- cache behaviors, then delete the cache policy.
--
-- To delete a cache policy, you must provide the policy\'s identifier and
-- version. To get these values, you can use @ListCachePolicies@ or
-- @GetCachePolicy@.
