Very difficult task:

  • use sessions with a very small timeout / you will have an expiration /

  • use hidden script / iframe for ping server / you will have connection /

  • handle the onunload event in the window / can be bypassed /

Code example:

window.onunload = function () { if((window.event.clientX<0) && (window.event.clientY<0)) { window.open("logoff.aspx"); } }

It is impossible for your application to know that the user has closed the browser. Session will be closed based on Session.Timeout

If the user does not refresh or request the page during the wait period, the session ends.

You can determine what should happen when the session expires in Global.asax.cs.

 protected void Session_End(Object sender, EventArgs e) { // Do stuff here... }

Edit: The web server does not know that you have closed the web browser.
