HTTP_CACHE_POLICY_TYPE enumeration (http.h)
The HTTP_CACHE_POLICY_TYPE enumeration type defines available cache policies. It is used to restrict the values of the Policy member of the HTTP_CACHE_POLICY structure, which in turn is used in the pCachePolicy parameter of the HttpAddFragmentToCache function to specify how a response fragment is cached.
