In general, it does not strike me as a good idea to have JavaScript
tracking whether the user is logged... knowledgeable users could
probably get around this fairly easily. In your cfm file redirect
them to a login page rather than trying to do it on the javascript
side of things.
You might want to look at the 'evalScripts' parameter (http://
www.prototypejs.org/api/ajax/updater) and have your cfm file
dynamically generate <script> tags depending on whether or not they
are logged in.
