I'm using a WebBrowser control to post to a URL which is password protected. I'm supplying the authorization header but internet explorer still shows the user password popup when it is opened.

webBrowser.Navigate(url, "_blank", Encoding.ASCII.GetBytes(postData), "Content-Type: application/x-www-form-urlencoded" + Environment.NewLine + "Authorization: Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(userpassword)) + Environment.NewLine);

What's more peculiar here is that it doesn't work even if you supply the correct credentials there when the browser window is opened. The popup keeps reappearing.

And it works if I remove the header from above call and supply correct credentials in internet explorer popup window.

@Mukund_Roy my question is specific to WebBrowser.Navigate not with HttpWebRequest – user1004959 Dec 31 '12 at 13:16
Maybe a dumb question but is userpassword username:password? – C.M. Dec 31 '12 at 14:45
are you sure that userpassword must be passed as header and not as part of POST data? – VladL Dec 31 '12 at 17:35
@C.M. Yes, it is username:password – user1004959 Dec 31 '12 at 18:04
@VladL Yes, because it is http authentication put by server using .htaccess – user1004959 Dec 31 '12 at 18:04
