pro_jsp thread: jsp and javascript - REPOST

Greetings all,
Currently, I am using javascript to catch all user actions that cause
onUnload() to be triggered in a jsp page. I'm doing this in order to know
when the user has closed the browser via the x button (by eliminating all
other possibilities). It works fine for all links and included jsp pages,
except that each page includes another jsp page that includes a submit form.
This page doesn't seem to recognize the parameter I'm using to tell each
link/action how to behave. All pages are contained within a window created
with javascript. I'll include some code and explanation below. I hope
someone can help me past this final hurdle. :)
Each page has the following <body> tag :
<body onLoad="closing=true" onUnload="if(closing)
window.location='http:/servlet/net.ftt.foundation.ControllerServlet?Task=net
.ftt.soc.LogOut';location.reload();">
This allows me to set closing to false on all other links/actions if I don't
want the LogOut task to trigger. An example of this is :
<td><img src="../webapp_images/accountsTabs.gif" width="154" height="20"
usemap="#AccountsTabs" border="0" onClick="closing=false"></td>
I can even use the closing variable in jsp-included pages as shown above.
However, it seems that if the jsp-included page has a submit form, the
closing variable and its value are out of scope (or just ignored).
Example :
<jsp:include page="/UB/CustMgtSidebar.jsp" flush="true"/> <-- This page has
links to other functions, but no form
<jsp:include page="/UB/CAMAddComment.jsp" flush="true"/> <-- This page has
the submit form
Any insight into how to work around or resolve this is greatly appreciated.
Thanks in advance,
