Net module changes to support caching responses to a POST request.

The solution is to add a user-defined identifier to UploadData.  If that identifier is set, and if the request method is POST, then HttpCache will enable caching for the response.  (The cache key will be a composition of the identifier and the URL.)  A subsequent POST request to the same URL with the same identifier will "hit" the previously generated cache entry.  Reuse from the cache is subject to all of the standard rules.
