Question

User1082734430 posted

Hi,

Can you please suggest me the approach how can i clear the session on browser close. 

I googled it and got many links, i tried to use  "onbeforeunload" event in jquery.  But this method is called even on redirection of the page. So i need to identify is it a browser or a redirection. In case of redirection i don't wanna do anything.

I also tried Application_End and Session_End events but of no use.

 Please suggest me the approach how can i go ahead.

Hi,

IMO the best option is to educate your users (on the login page) so that they use the "logout" link made available to them. Basically you have no way to know (at least a reliable way) that the user closes the last window on your site.

Perhaps later (if I remember there is a Windows api being worked on).

My 2 cents,

• If you are storing session in memory (default option) then I afraid there is no perfect solution. You can go what Naseer mentioned.
• If you are storing session in SQL database then you can clear session via Job (handled by SQL Server Agent).

But before that, you should ask yourself why you need to clear session on browser close? Is large session item object affecting the scalability of the system? Is yes then it's better to find alternative solution.

truly speaking, there is no way of distinguish  between browser close and normal navigation using unload event,

only thing u can do is,  set a flag at client side on click of any navigation and check if that flag is true in unload event then it is navigation unload. in this case let the unload happen.

else ask to leave or not, on leave do service call to server to end the session
