Let's say we have a WinHttpRequest object that works, it provides
similar interface as IXMLHTTP.
Why should I use urlmon for that? WinHttpRequest should stay in winhttp,
and won't use urlmon.

Thanks, will take a look.

Why IXMLHTTPRequest is IE related? Or you mean that anything that uses
internet should go through urlmon?
