Take this with a grain of salt because I haven't really 'studied' CF since 4.5 for my certification. I have found out that my cert has since expired too. I'm not sure if 67 is a lot because it depends on how large your application is. I read through the docs and it looks like you still need to CFLOCK the session variables to ensure data integrity. Personally, I try to avoid session variables. Basically, I use it for user-login related functions. Not sure if this is the best use. I always ask myself is there another way to do this without using session variables but without using cookies. I will generally submit that solution. I would take a look at said solution if QA submits a ticket about system performance but that hasn't happened yet. I'm curious what other developers think about this. I'm currently on a project where these decisions are out of my hand and I have a slew of application and session variables that I have to use. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-community/message.cfm/messageid:282370 Subscription: http://www.houseoffusion.com/groups/cf-community/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5
