Session_End does not fire?

I want to sign out a user when his session times out. So used following code in Global.asax:

protected void Session_End(object sender, EventArgs e)
{
FormsAuthentication.SignOut();
}

But seems `session_end` never fires. Any idea how can fix it? I'm using ASP.NET with default settings.

Are you sure that it never fires ?

As I understand it `Session_End` has nothing to do with the current request because ASP.NET session is terminated by the timeout AFTER the last request from the client has arrived. The call to `FormsAuthenticaion.SignOut` manipulates authentication cookies and therefore has no effect without any connectivity from the client (browser).

Take a look at this question (which has an answer) - the problem is more or less similar to yours so you might find a right solution:

[Session_End in Global.asax.cs not firing using forms authentication][1]

Hope this helps.

In your web.config you need to have the sessionState element as a child of the <system.web> element

<configuration>
<system.web>
<sessionState mode="InProc" />
.....
</system.web>
</configuration>

You may set some Session data in Session_Start. Without this, Session_End will not be fired.
see [this][1]

> Also another very important thing to note here is that if you do not save anything in the session the Session_End event will not fire. There must be something saved in the session atleast once for the Session_End event to fire. This also means that if you save something in the session in the first request and abandon the session in the same request the Sesison_End event will not fire, as there was nothing saved in the session ever.

I dont know how its working, but it will fire when i close my browser after time out period.

public void Session_End(Object sender, SessionEndedEventArgs e)
{
}
Call this from

Application_Start() Event

SessionEndModule.SessionEnd += new SessionEndEventHandler(Session_End);

I don't know if it is a feature or bug. Or may be I don't understand enough session managment in ASP.NET. But this is what I found.

Session_End does not fire in ASP.NET MVC 4 (with default settings for sessionState element in web.config) if Session_Start is not declared.

So you need declare Session_Start to catch Session_End :)

protected void Session_Start(Object sender, EventArgs e) { }

protected void Session_End(Object sender, EventArgs e) {
Debug.WriteLine("End. " + Session.SessionID);
}
