You can pretty much take Jon Hall's post and add 'me too' to that. I had horrifying experiences with disappearing session vars, mostly related to code running on shared servers and the instability that comes from relying on memory-based storage. Using cvars for session management insulated my apps from cf service restarts, even cold reboots, so long as the next page request falls within the inactivity-based 'session' expiration the app still retains the user's session. Now, that's not the same environment as a cluster at all, but take that and couple it to the hoops necessary to jump thru when using an app that requires a lot of persistent vars (i.e. Step 1: copy to request scope. Step 2 process Step 3 copy back to session scope, and use locks... Or lock everything individually everywhere) compared to the relative simplicity of simply using cvars in code. I never missed the inability to store complex values given the ability to use CFWDDX to handle that issue. This is extra coding just like the locking I was whining about above, but my frequency of need for complex values isn't anything like the frequency associated with locking, and planning efficient use of same. I've never had a site that had high enough traffic to be able to notice the load coming off the cvar storage db, so I can't say at what point a cvar-based session management scheme will fall down where a svar-based one will not. To me, cvars are simpler to use and are, in my admittedly not all-encompassing experience, inherently more stable given their more permanent storage medium (a db, of course). Question: CFMX uses J2EE's session variables. I'm not up on this at all, but doesn't that mean I have to be using the much more expensive Enterprise for J2EE?
