.net - Using An HttpWebRequest To Access Multiple Pages?
Apr 30, 2012I'm trying to screenscrape a website that requires a POST login authentication. I can authenticate fine on my first request, but when I attempt to turn back around and hit the next page, I get a redirect back to the login page (basically it's saying I'm not logged in).

Also the XYZCustomerServiceUserName and XYZ values are stripped. Other than that, the session information is identical between the two connection attempts.
