How to Call serverside function from client side code
I am creating an application, where I am dealing with userStatus (online/offline). When user will close the browser window i want to call a server side method which will abandon the session and update the user status.
I am not using Ajax/ update panel for my application.
My code is --
<head>
<script language="javascript" type="text/javascript">
function HandleClose()
{
alert("Killing the session on the server!!");
// here I want to call a server side function
}
</script>
</head>
<body onunload="HandleClose()">
