Session_End event....

shawnm · August 17th, 2004, 12:06 PM

I am writing a user tracking function that I'm calling from protected Session_End event in the global.asax file. This function looks like this:

Code:

        protected void Session_End(Object sender, EventArgs e)
        {
            if(Session["ID"] != null)
                member.endSession(Int32.Parse(Session["ID"].ToString()));
        }

The endSession function make a DB call that sets a flag in a table. This ends up ending some logged in users sessions, but not all. And the timing is incosistent. Is there a better way to do this? When is this event fired?

Thanks,

The Session_End event fires when the session does end for a user, so I don't see how it would be an inconvenience... if you don't want the session to end, increase the session timeout property.

It is not incovenient - in fact its quite the contrary; very easy to use. It doesn't work every time though. Some sessions seem to never end (the Session_End event doesn't fire) and the database calls are never made, leaving the user "Online". I am wondering what causes the session_end event to fire and if there is some circumstance that would prevent it from doing so?

Hey,

As long as you are in InProc session state, it should fire. If the session state is set to use a state server or SQL Server, session_end will never fire.

The ways to exit the site are:

- User navigates away from site
- User closes the browser
- Browser crashes

I think the first one would be fine; don't know about the other two.

A crashed browser? We can't be talking about IE...

Thanks for your help - I will verify that we're running our app InProc.
