Fortunately, there's very little that's specific to CF with clustering. Don't use Session variables, and if you need to distribute non-database content (uploaded files, for example) you'll need to find a way to use a common storage device or a way to distribute those files across servers as needed. For Client variable management, you may want to use the SETDOMAINCOOKIES attribute, depending on how your cluster is set up. > In a nutshell I guess I'm making the jump from CF > Professional to CF Enterprise :) Not necessarily. If you use hardware-based clustering, you can continue to use CF Professional. If you want to use software-based clustering, CF Enterprise provides ClusterCATS. I'd recommend hardware-based clustering, personally, if it's an option.
