ASP.NET Session End Redirect

peter2004 · February 24th, 2006, 01:59 PM

Hi,
I have tried to automatically redirect by application to return back to my login page when session end by putting a redirect code in global session_end method, but it does not redirect even though the method was called. How would I redirect to another page automatically when session expired?

Thank you,
Peter

You can't. Period.

SessionEnd is never associated with a request; it fires at the server without a browser / client context. There is no way to redirect a client from the End event, because there is no client.

Cheers,

So, there is no other way except using timer or JavaScript which is not neccesary synchronize with SESSION state?

If you want to redirect to Login.aspx when the session has expired, can't you just always redirect to the Login page when the user hasn't logged in?

In addition to that, you can set a cookie that the user has previously logged in and use that cookie to determine where to redirect when they start a new session.

Yes, you are correct if you use cookie as you mention or check for session count in Global Global_AcquireRequestState event. Nonetheless, this require user intervention. In another word, when the session or cookie expired, the page doesn't redirect until user refresh the page or do something to the page. What I would like is the page to expire or redirect automatically without any user action. I was able to redirect by using javascript.

True. But to make it even simpler, you can add an HTML <meta> refresh tag to the page. If you set the refresh period to just under or over your session timeout (depending on whether you want to keep the session alive, or want to redirect to the Login page directly after a session timeout) the browser automatically takes the user to the requested page after a certain amount of time.

I think the "Thank you for your contribution" page that I am about to see when I click Post New Reply in a few seconds uses that technique....
