Dec 21, 2011I have a bit of strange behaviour in an asp.net web application that involves the session state being lost.
Process A user logs into the application and the session is set. They then fill out 1 field, and the application then does an AJAX POST to a .asmx web service. Within the web service, I am using a HttpWebRequest to grab data from another server.
This data is then output to the browser.A few more fields are then filled in, and the data is then again Post to the same web service via an AJAX POST.

VS 2008 Submit Form Using HttpWebRequest
Oct 27, 2009The below code allows me to login to a site using HttpWebRequest however I can't login to the site [URL] (which is the one I want to login to). At the bottom of the code I write the source to a file and upon opening it simply shows the login page.
After looking at the source I believe the issue is caused by the form calling a javascript funciton to actually submit the form when the 'Login' button is clicked. Has anyone had this type of situation in the past and if so what was the solution to get the form to submit?

Nov 30, 2009I'm using the following code to set the proxy on an HTTPWebRequest:

request.Proxy = curProxy
