I have a small requirement..

if the user dint sign off or log off then he try's to close the browser IE clicking on 'X' (top right of IE or Firefox browser ) then i need to ask a conformation message like "Are you sure you want to close ?" ...
I am using Master page in my application and i tried the event : "window.onbeforeunload " in my master page its works fine, shows an alert(conformation) message. but if i press back button on the browser(IE on IE or Firefox) then also its firing(but it should not) is there any way to full fill my requirement ..I hope i had explained u clearly...if not pl z let me know........

what i mean to say is.. if the Session("USerid") is active or if it contains any value ie.
at that moment if user trys to close the browse(click in 'X'/Close button browser either IE or Firefox ) it should give prompt a message "are u sure do u want to close?"..

Not that it matters to you but I truly hate these kinds of popups!

call button log off event to this code

<script type="text/javascript">

     window.onbeforeunload= function(){

   if((window.event.clientX<0) || (window.event.clientY<0))

         document.getElementById('<%= btnLogoff.ClientID%>').click();
