When is Session_End() called in ASP.NET MVC ?

Question

I have configured my Web.Config file as follow in a ASP.NET MVC 2 project:

<sessionState mode="InProc" timeout="1"/>

And added the following in Global.asax.cs:

protected void Session_End(object sender, EventArgs e)
{
    System.Diagnostics.Debug.WriteLine("Session_End");
}

protected void Session_Start(object sender, EventArgs e)
{
    System.Diagnostics.Debug.WriteLine("Session_Start");
}

Session_Start() is called when a new user goes on the website. I would have expected Session_End() to be called after 1 minute of idle time, but it's not the case. Am I missing something?

Answer 1

Be patient. The event should be called, but not necessarily right after the timeout.

You could try from a Browser: Start a session,wait > 1 minute, do a Postback somehow

This should help to verify that the Timeout works and I think you will also see the SessionEnd happening at that time. Otherwise, just wait and start some other sessions. The system will come around o calling it sometime.
