Infact onUnload will be called even when u r going from one page to another !!
Here is a guess :
I haven't used Citibank website, but my guess is that it actually does not log you out when you close the window. Instead when u try returning to the website, it recognises that you are not using a valid previous page to come to the requested page, and it logs you out at that point.
In a typical MVC model :
1. The only way to go from one page to another is via a Controller Servlet.
2. Any direct access to a page (jsp) is denied. Any attempt for direct access, sends the user to login page.
===
In any case , here is a not-very-nice way to achieve what you want via javascript, assuming there was one link on my page. This gives u a general idea :
<html>
<body onLoad="closing=true" onUnload="if (closing) window.open('thanksForVisi
<a href="nextpage.htm" onClick="closing=false">Cl
</body>
<html>
If u ask me, user should indeed get logged out if he tries to refresh the page. This is the behavior in citibank site too... infact this is what they have done :
1. Removed all toolbar buttons from the window. So user cannot hit refresh.
2. Even the refresh available via right click popup menu is disabled i think.
ICICI Bank logs you out if you hit refresh, try to move across the website by clickin Browser Back/Forward buttons etc. The only valid way to move across pages for them is to hit the Previous/Next etc. buttons and link provided on the pages.

You can use onUnload.....
function forceLogoff(){
window.open("/servlet/Logo
}
and put this in yout body tag
<BODY onUnload="forceLogoff()">
It will pop up a logoff page.
