In one application, I used a session variable which pointed to the
database. In the application.cfm I check the database for the last
usage date-time for that user.
If more than 15 minutes I present the login page, if less than that I
update the database with now() as the last usage time.
This was to protect against a user walking away from the PC while logged
in but it also has the virtue of acting as an automatic logout.
