ColdFusion SESSION variables time-out – this is part of their design, after a period of inactivity they disappear. The time-out interval is specified when SESSION state management is enabled – in the tag. But sometimes SESSION variables will time-out quicker than they are supposed to. Why is this? Because the maximum SESSION time-out value is specified in the ColdFusion Administrator as a server-wide setting. If the interval specified in is greater than the maximum interval specified in CF Administrator it’ll not be used (the Administrator maximum will be used instead). (Applies to: ColdFusion 3 (or later))
