"The documentation incorrectly states that setting cookie on the same page you use cflocation would result in the cookie not being set. The cookie will be set correctly. Stephen M. Gilson Macromedia" http://livedocs.macromedia.com/coldfusion/6/CFML_Reference/Tags-pt166.htm As of MX, the CFCOOKIE/CFLOCATION issue isn't a concern anymore, right? > The above assumes you don't have situations where a race condition can > arise.

It's obvious why you need to CFLOCK writes to the application scope since there are likely to be many users accessing application scope variables all over the place. I've heard that locking session variables is important if you use frames or if a user were to repeatedly hit the refresh button on a page where session variables are written to unlocked. My question is, does CFLOCK scope=session type=exclusive impact performance significantly? Or for that matter, would a type=readonly impact it as well? I don't know enough about CFLOCK and whether it's locking just that users' spot of shared memory or the entire area of shared memory where session vars are stored. If it's the former I'd guess the performance impact is negligible, and in the case of the latter I'd guess it's significant. I've gotten in the habit of locking session variables EVERYWHERE because of the serious concerns pre-MX, but if this is having a negative impact on performance I'm not aware of I'd appreciate it if someone would let me know - thanks :) -Cliff ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:205970 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
