OnSessionEnd delete username from applicationlist

Question

Hi everyone,
I need some help with the OnSessionEnd function within my
Application.cfc, let me explain:
When users log in to the website their username gets stored
in an application list 'users' (so I can show the users currently
online on the website, for example.). When a user clicks the logout
button I delete them from that list, everything working like it
should be here. But when users just close their browser window they
don't get logged out, so I have set a sessiontimout value and use
an OnSessionEnd function.
Now my question is, how do I delete the user from the list
within the OnSessionEnd function? How do I search for a user that
is already gone -> can't search for #GetAuthUser()# since he is
already gone).
I hope you understand what I'm trying to say :)
Anyway thanks in advance any help is much appreciated!

Thanks for the comments but it's not working yet, I modified
the code a little bit, this is what I have now:
on login:
<cfset #SESSION.u_naam# = #FORM.loginusername#>
<cfset #SESSION.u_ip# = #CGI.REMOTE_ADDR#>
<cflogin>
<cfloginuser name='#login.ledenNickname#'
password='#hash(login.ledenPaswoord)#'
roles='#login.ledenRechten#'>
<cfset application.users = ListAppend(application.users,
'#SESSION.u_naam#(#SESSION.u_ip#)')>
</cflogin>
application.cfc onsessionend:
<cffunction name="onSessionEnd" returnType="void"
output="false">
<cfset findUser = #ListContains(application.users,
'#SESSION.u_naam#(#SESSION.u_ip#)')#>
<cfif findUser EQ 0>
<cfelse>
<cfset application.users =
#ListDeleteAt(#application.users#, #findUser#, ",")#>
</cfif>
<cflogout>
</cffunction>
I made a 'checkpage' to see what's in the list
application.users and what's in the sessions u_naam and u_ip, when
my session ends (put a 10 second timeout) and I go to this page, I
see that the application.users list hasn't changed, but I do get an
error that the sessions u_naam and u_ip are not found... (so the
session really did end).
The only thing I can think of is that my "onSessionEnd" code
in the application.cfc isn't executed... I do a ListContains in
that function and I already tried to set the application.users list
to "bleh" if the findUser variable was 0 and even that didn't work
:), it just doesn't get executed I think.
Any help? :)
Thx
