How do I get ASP tofire off code when the user clicks the "X" box or close tab function on a web page?

My application tracks specific user data in its own "SESSION" table in the database. When the user clicks the "Logoff" button, I have no problem clearing his/her entries from the session table. I need to perform the same function when the user clicks the X at the top right corner of the browser or when they click the close X on the tab. My first instinct was to create a Page_Unload method but I'm not sure what close event has to occur to call this. I've also placed code in my Application_End and Session_End segments of the Global.asax file. None of this seems to work. My question: Is there a specific event that fires when the user closes a browser/window that I can attach my code to so that I can do a "clean" logoff of the user from the database? I've researched this for two days and can't find a straight answer from anyone. Thanks in advance.

As far as i know, you can only get it via javascript.

works for 'X' or Alt+F4 or Tab

<head runat="server">
    <title></title>

    <script type="text/javascript">
        function HandleOnClose() {
            try {
               alert("window is closing");
            } catch (err)
            { }
        }

    </script>

</head>
<body class="Resolution_1024x768" onunload="HandleOnClose()">
    <form id="form1" runat="server">

blah blah blah

</form>
</body>

Open in new window

I don't think I can do what I need to do in javaScript. I need to call a C# method - logoffSession() - that accesses a database service to delete the user record from the database. I believe this call needs to be triggered by some event when the page/browser/tab closes. I need to identify what that trigger is...

I will prefer the same way what abhinayp mentioned. As this is the common technique used in the industry when we want to handle this sort of situation.
