I haven't used client vars in quite some time... No need. But when I did it was with a 4 server CF5 NLB array with an active/passive SQL2000 cluster. The CF machines had a separate SQL instance dedicated to client storage and to be honest, the only problem we had was dealing with the extra bandwidth that the back end needed when we got into the realms of 3000 simultaneous users... In the end, it wasn't the client var traffic that was causing the problem. We solved the bandwidth issue by moving the source code onto the web servers instead of them using the filestore server and used robocopy to keep them in sync... Nowadays I'd use SVN to deploy :) Once we had solved the bandwidth problems, everything was fine. We never had any issues at all with client storage but I will say this... We designed the app from the very beginning to use client storage. We didn't port the code from session etc. I think when you do the latter, you are asking for trouble... As long as you plan well and understand the limits of the client var scope then you should be fine. As an aside, watching SQL profiler do it's thing on a live database with 3000 users on the site is a great way to scare yourself! The speed of the transactions going through is something else!
