Jim, So lets say I have code at the top of every page in my application that checks for the existence of certain session variables and if it doesn't find them redirects the user to a login page.
You're saying that I could define this once in application.cfc and set the behavior for the entire application? Tthis could be a huge timesaver for me in building portals.
