you can set an event handler for window.onunload (client side script), and then do an XMLHTTPRequest.

Did a lil googling, the problem with this solution is that it does not only fire when the browser is being closed but I guess its a start.<html>
<head>
<title>onunload test</title>
<script type="text/javascript">
window.onunload = unloadPage;
function unloadPage()
{
alert("unload event detected!");
}
</script>
</head>
<body>
<p>Reload a new page into the browser<br />
to fire the unload event for this page.</p>
<p>You can also use the back or forward buttons<br />
to load a new page and fire this event.</p>
</body>

oh cool i tried that and it works but i jus realsied that i cant use javascript to update a value in a database. i was trying to whenever someone leaving the site i would capture the time the left the site and update it in the database
I believe you can track sessions natively in asp.net, I remember seeing an example where they used that fact to make a hit counter and to show the current amount of online users. Where every time a session times out you subtracted 1 every time a session is created you add 1.
yes but in this case it wouldnt be a time out the person got timed out they prob jus left the website. thus in essense its the page unloading i want to capture that time and log it to a database.

For a page unload you will need the following sub procedure
[VB.Net]
Private Sub Page_Unload(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Unload
End Sub
i am thinking of doing the following it seems a likkle bit sloppy at the moment going to still try a better way of doing it though
<script type="text/javascript" FOR="window" EVENT="onunload">
new_window = window.open('default.aspx','default', ' menubar,resizable,dependent,status, width=300,height=200,left=500,top=10')
</script>
1. they will still be able to be redirected to the website they entered or the window will still close if they clicked the exit button
2. a new window wid open that jus displays a good bye message jus for sure and then within that i going to log the log out time and any other information i wanted to set in my database
