What is different between HttpCacheability. NoCache and Response . . . a) An abstraction over the response object's caching policy that can be useful in testing scenarios b) Potential future-proofing if the HTTP spec is extended for some reason to mean that NoCache needs more headers in the response, or other tweaks to the response
