Islogged on question, need help

Question

Hello;
I wrote a small app that makes the user log into it to get to
features. I wanted to know how would I go about letting a user that
logs into it, know that other users are logged in at the same time?
They have to be added to the usermanager that is part of a
DB, it is also controled by sessions in cf8.
How would I write a script that would say:
user1 is logged on
user2 is logged on
As many users that are logged on in a list.
Can anyone help me out with this?
Thank you.

This is what I am looking for. BUT when I add the code to
mine, I get an error. It is saying that
Element SESSIONTRACKER is undefined in APPLICATION.
The error occurred on line 16.
I tried adding my code for teh application.cfc file to both,
my main application file as well as the one that is in the
protected directory I am trying to use the session tracker in.
This is my code in the application.cfc file in the protected
directory:
<cfcomponent output="false" extends="ProxyApplication">
<!--- this is supposed to define sessiontracker in the
application.cfc file --->
<cfparam name="application.sessionTracker"
default="#StructNew()#">
<!--- end sessiontracker --->
<cffunction name="OnRequestStart">
<cfset super.onRequestStart() />
<cfif IsDefined("COOKIE.CFID") AND
IsDefined("COOKIE.CFTOKEN")>
<cfset cfid_local = COOKIE.CFID>
<cfset cftoken_local = COOKIE.CFTOKEN>
<cfcookie NAME="CFID" VALUE="#cfid_local#">
<cfcookie NAME="CFTOKEN" VALUE="#cftoken_local#">
</cfif>
<cfif not StructKeyExists(session, 'isValidUser') or not
session.isValidUser>
<cflocation url="../sitemanager.cfm" addtoken="yes">
</cfif>
</cffunction>
<cffunction name="onSessionStart" returntype="any"
output="true">
<!--- this is sessiontracker code for application.cfc
--->
<cfif isDefined ("session.login_id")>
<cfset dummy = structInsert(
application.sessionTracker,
session.login_id,
now(), true)>
</cfif>
<!--- end sessiontracker --->
</cffunction>
</cfcomponent>
What am I doing wrong? how is it not defined in
application.cfc?
