-- Updates a response headers policy.
--
-- When you update a response headers policy, the entire policy is
-- replaced. You cannot update some policy fields independent of others. To
-- update a response headers policy configuration:
--
-- 1.  Use @GetResponseHeadersPolicyConfig@ to get the current policy\'s
--     configuration.
--
-- 2.  Modify the fields in the response headers policy configuration that
--     you want to update.
--
-- 3.  Call @UpdateResponseHeadersPolicy@, providing the entire response
--     headers policy configuration, including the fields that you modified
--     and those that you didn\'t.
