If you are using master pages in your application, you wont have to write same code on each page. On other thought, you can create a base page and write code to inject javascript function using ScriptManager. And then make all pages to inherit the base class.

There is no any permanent connection between your browser and the server. So you need to detect browser close event from client side (browser) and then call server event to execute your code. You can use master page to avoid writing repeating code on each page. Find following code for the same. 1. To enable page methods
<asp:scriptmanager id="ScriptManager1" runat="server" enablepagemethods="true" />
2. Detect browser close event.
<body onunload="HandleClose()">
3. Call pagemethods to invoke server side event.
<script language="javascript" type="text/javascript">
//<![CDATA[
function HandleClose()
{
alert("Killing the session on the server!!");
PageMethods.AbandonSession();
}
//]]>
</script>4. Define your page methods at server side and call your code.
[WebMethod]
public static void AbandonSession()
{
HttpContext.Current.Session.Abandon();
}HTH

If you have a button or an imagebutton in the masterpage you can place the next code in you HandleClose() function:
__doPostBack('<%= Button.UniqueID %>','');or__doPostBack('<%= ImageButton.UniqueID %>','');In that case you come in the OnClick event of the button or the imagebutton and there you can handle the Abandon of your SessionIn Word you can only store 2 bytes. That is why I use Writer.
