Using Session_End in Global.asax

[evaleah]

I want to be able to record when a user discontinues use of my application by calling a SQL stored proc. I have put the call in Session_End in my Global.asax file and it doesn't seem to ever get called. I tried the same thing in Application_End but I think that is not really the place I want.

I can successfully record when they log on using Application_Start. Is there something I am missing to get the same thing when they leave?

Thanks!!!

The session takes a while to time out. The client doesn't keep a line of communication open with your server (it just makes a periodic request), so your server can only assume when a user's session should end (and the server will wait X amount of time before making that assumption).

Try changing the session timeout and see if you get the results you want.

evaleah,
Session_End is the right place to put your code but remember that the Session_End event will not be fired until the Session expires. Your web.config file contains an entry that sets the number of minutes of inactivity that must go by beofore a session will expire. The default value is 30 minutes I believe. This means that the code in Session_End won't run until 30 minutes after the user closes its browser.

For testing purposes, set the timeout of your sessionState to 1 minute in your web.config file, as in:

<sessionState mode="InProc" ... timeout="2"/>

Then, run your application; don't do anything for a minute, and check that the code in Session_End gets executed.

My timeout is set for 20 minutes in my web.config file. For testing I waited until session timed out. I got the friendly session time out page I had created but the event in my global.asax didn't ever fire. Any explanation for why that would be?

I have only tried this in my test environment. Does that make a difference?
