CLIENT variables are one of the ColdFusion variable types that may be used to maintain client session state. In addition to any variables you create within the CLIENT scope, there are six variables that always exist: CFID contains the client ID, CFToken contains the client token, HitCount contains a request counter, LastVisit contains the date and time of the last visit, TimeCreated contains the date and time of the first visit, and URLToken contains a CFID and CFToken suitable for embedding in URLs of your own. (Applies to: ColdFusion 3 (or later))
