to call Session_End() event when user closed Browser

There is no event in the Global.asax to deal with browser closing. When we need to call Session_End() upon user close the browser.

<script language ="javascript">

function CloseWindow()
{
window.location = '../clearance.aspx';
alert('You are about to close the window');
}

</script>

 

3.in the Page_Load() of Clearance.aspx, add the following code to fireup Session_End() or do clearance(Attention, make sure your web application is in the In-Proc Session mode, web.config use In-Proc Session mode by default).

HttpContext.Current.Session.Abandon();

// to do clearance bellow:
