Redirect to Error Page on ASP.NET Web Forms Session Timeout

Hi,

In my website I have around 10 screens, each of which display a session variable.

I have seen that the function  void Session_End(object sender, EventArgs e) of Global.asax is called when session expires. But redirecting to session timeout page by doing  Response.Redirect will not work there.

 

Can anyone please help me with a way to redirect to error page from Session_End function of Global.asax.

You are most welcome to give me any other approach to handle session timeout at one place, instead of checking session variables in each and every screen and appropriately redirecting to error page.

Hello nancy1985,

I suggest that you take a look at the following forum thread, discussing similar issue – http://forums.asp.net/t/1137344.aspx.

I hope this helps.

Hi nancy1985,

If you still need assistance on the matter, please do not hesitate to ask.

Hi Nikolay,

I have gone through the link and have found out that the only way to achieve this is to check the session status in each and every page and redirect to an appropriate error page if session is invalid.

Please let me know if otherwise.

Hi nancy1985,

This is one possible approach. You could also handle the session end using javascript, similar to the following:

         var sessionTimeout = "<%= Session.Timeout %>";

        $(document).ready(HandleSessionEnd());

 

        function HandleSessionEnd() {

            sessionTimeout = sessionTimeout – 1;

            if (sessionTimeout >= 0) {

                //call the function again after 1 minute delay

                window.setTimeout("HandleSessionEnd()", 3000);

            }

            else {

                window.location.replace("Relogin.aspx");

            }

        }

 

Let me know if you have any questions.

Hello nancy1985,

If you have any other questions, please feel free to contact me.

Thanks David Young.

I took up the approach of checking the Session validity in the Page_Load and acting accordingly.
