How to call Session_End when a browser is closed?

Question

I have two questions. I will split my questions into two sections and give an overview. I'm not entirely sure of the code I need to post so if I have missed some out, please let me know and I will help.

Overview:

When the browser is closed I need to sign the user out.

Question 1:

How do I call Session_End when the browser is closed?

I did some reading on how to close it and it seems that the only way to detect if a Session has ended when a browser has been ended is by using something called 'InProc' in my web config. I gave it an attempt and it didn't seem to change anything at all. So I'm wondering if there is another way around this.

Session_End:

 protected void Session_End() {
            if (User.Identity.IsAuthenticated) {

            }
        }

Question 2: How to sign a user out on Session_End?

Once the program has called the void I need to sign the user out as it's causing a bug in my program. I am using the Authentification manager.

Session_End:

protected void Session_End() {
            if (User.Identity.IsAuthenticated) {
                AuthenticationManager.SignOut();
            }
        }

Using InProc sessions, the Session_End method is called when the session times out. This is (by default) 20 minutes after the user has last accessed your site (requested a new page). Note that these 20 minutes could have been spent carefuly reading a single page of your site - his session is still closed.

There is no way to detect when a user has closed his browser or navigated away from your site.

You need to use the Global.asax file. It should already contain this Method, all you need to do is add the guts of your code.

protected void Session_End(object sender, EventArgs e)
{
    if (User.Identity.IsAuthenticated)
    {
        AuthenticationManager.SignOut();
    }
}

Yes, but Session_End is still not called when the browser is closed. Apparently you cannot detect when a browser is closed and run the code anyway – Andrew Kilburn Aug 18 '15 at 12:02
