Really, I have a pretty hard time thinking of a good use case with race conditions that goes beyond a contrived impractical example. Banking maybe? Though in most cases I'd going to be doing much of that type of work in the DB and even if I'm not, it's probably going to be in a scope that doesn't live past a single request. Most of the examples I see are things that shouldn't be using the Session scope at all anyway. Of course, folks are free write their apps any way they want, but I just don't see it as a problem. I very very very rarely lock (or have need to lock) session vars. I don't think I've personally found reason in any project I've worked on since CF5. -Cameron -- Cameron Childress -- p: 678.637.5072 im: cameroncf facebook <http://www.facebook.com/cameroncf> | twitter<http://twitter.com/cameronc> | google+ <https://profiles.google.com/u/0/117829379451708140985> ... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:349765 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
