Well IT IS actually possible for the browser to inform the server that it
has been closed.! You would have to do the scripting via JavaScript though.
You could set a onunload() event handler for the window. This onunload event
handler could then call a server-side script with the parameter close=true.
The server-side script could then use this information to perform some-clean
up operations. However the sever-side script SHOULD NOT write to the client,
because by that time IE/NS would have closed the window down.
A rough outline of how this works is like follows :
<script language="javascript">
window.onunload = function() {
location.href="detect_close.jsp?close=true";
}
</script>
You could do whatever you want in the JSP. Note that the JSP WILL KNOW which
client has shut the window, because the browser would send the
session/cookie data in the request just before the window shuts down.
