I want to clear session on browser or tab close. I am using below script for that but its not working.

HTML

  <script type ="text/javascript" >
         var clicked = false;
         var xmlHttp
         var browser = navigator.appName;

         function CheckBrowser() {

             if (clicked == false) {
                 xmlHttp = GetXmlHttpObject();
                 xmlHttp.open("GET", "Default.aspx", true);
                 xmlHttp.onreadystatechange = function () {
                     if (xmlHttp.readyState == 4) {
                         // alert(xmlhttp.responseText)
                     }
                 }
                 xmlHttp.send(null)
                 if (browser == "Netscape") {
                     window.location = ".../Default.aspx";
                     alert("Browser Terminated");
                     openInNewWindow();
                 }
             }
             else {
                 //alert("Redirected"); 
                 clicked = false;
             }
         }

         function GetXmlHttpObject() {
             var xmlHttp = null;
             try {
                 // Firefox, Opera 8.0+, Safari
                 xmlHttp = new XMLHttpRequest();
             }
             catch (e) {
                 //Internet Explorer
                 try {
                     xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
                 }
                 catch (e) {
                     xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
                 }
             }
             return xmlHttp;
         }

         function openInNewWindow() {
             // Change "_blank" to something like "newWindow" to load all links in the same new window
             var newWindow = window.open(".../Default.aspx");
             newWindow.focus();
             return false;
         }
 
   </script>

<body onclick="clicked=true;" onunload="CheckBrowser()">

You can use on application_end event
In that you may do "session.abandon()" in global.asax
