Damien, The way I understand it is that SESSION variables are variables you set that reside in the application servers memory during the duration of the SESSION that the browser is connected.
CLIENT variables are persistent to that particular browser and can "stick" with it. Both can be used to store values, although, I don't believe that CLIENT variables can have structures, but I maybe wrong, I'll have to double-check. One of the reasons you would choose CLIENT or SESSION variables would be if your application is going to be in a "server farm", where you have 3 ColdFusion servers all running your application and all three point to one database server. Since the user might connect to the first server on the initial request, then the third server on the subsequent request, you wouldn't have access to the SESSION variables you set as they are on the first server. CLIENT variables, provided they are stored in the database or cookies (see the CF Admin for setting the storage of CLIENT variables) would be accessible. Yes, you could disable CLIENT variables, you don't need to use them with SESSION variables. -t -----Original Message----- From: Damien McKenna [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 23, 2004 11:34 AM To: CF-Talk Subject: FAQ: Client vs Session (vs Cookie) variables? Could someone please enlighten me to the differences between client and session variables? I thought I understood them but apparently am missing something with regards to ColdFusion's handling of them. Specifically: - What are the differences between Session and Client variables? I hadn't realized that there were client variables as well as session and cookie variables, I always considered client variables to be analogous to cookies. I guess my question comes down to this: if we have session variables why do we need the client variables? If I only use session variables in my code can I completely disable client variables?
