A Way to Grab URL of Webbrowser Control HTTP Responses 200 & 204

I need the following: When you navigate with webbrowser control (Must Be WebBrowser Control) for example to [login to view URL], WebBrowser Control will show the current url to "[login to view URL]" but if you use a tool like fiddler2 and analyze the HTTP traffic you can see the server gives (Responses) back http code 200 & http code 204 URL's. I need a way to access to those urls and have it as a string in my program. (I know the domain if this helps). Required: To work on .net 2.0 To work with webbrowser control To work on 32bit/64bit.
