Client variables last a lot longer, unless you delete them, default is 90 days. If you want information to last for a long period then client vars are good.
Session are useful when you only need to keep information for a particula r session, CF will delete the session variable when the user closes there browser. -----Original Message----- From: Neil H.

From what it sounds like why not just use client variables all the time?
