Is there a way to 'hook' WinHttpSendRequest so that one can report progress using a progressmeter.
It seems like its very easy to report progress on http based file downloads, but no way to do the same with http based file (or forms with large data block) uploads.

|MSDN says that this function can operate either synchronously or asynchronously. But as I can see it requires registering a callback function -- dwContext parameter -- plus setting WINHTP_FLAG_ASYNC flag.|
