I have no idea, and it's not documented anywhere, and shouldn't be. It's an implementation detail subject to change.

There should be no interference with shdocvw.dll. That's for web browsing, and has nothing to do with web services.

HttpRequest is a way that allows in code to mimic actual web requests like a POST or a GET request to a website.

Does it use the HttpWebRequst or...what is it doing behind scene?

is there any limitation on client connection to a server?
