how come i never pass through Session_End(..) in global.asax

[Franck]

Hello,
I'm trying to count the number of current user that way


public class Global : System.Web.HttpApplication
{
public static int nbUsers;
protected void Application_Start(Object sender, EventArgs e)
{
nbUsers = 0;
}
protected void Session_Start(Object sender, EventArgs e)
{
nbUsers++ ;
}
protected void Session_End(Object sender, EventArgs e)
{
nbUsers-- ;
}
....
}
}

but i never pass through the Session_End event
even if I call
Session.Abandon();

Am i Missing anything?

If you're saving Session out of proc (NT State Server or SqlServer) is won't
get called. Also, you should use Interlocked.Increment and Interlocked.Decrement
to modify the nbUsers in a thread-safe manner. As it stands now you're code
is not thread safe.

Thank you for your advice
but i'm not saving the session out of proc?

The default session timeout is 20 minutes. The web server has no way of
knowing when a client disconnects. So the event will only be fired when the
timeout is reached which is 20 minutes after the server was last connected
to by the client. Have you reset the timeout so it will fire while you're
still debugging?

Isn't it the job of the Session.abandon();
method?

Franck,

Session.Abandon is a method you can call to cause a session to end. After
calling Session.Abandon the Session_End event will be fired.
