ClusterCats is still in the CF documentation (for 6.1)
but I've found some references to ClusterCats in our internal docs. there's no mention of why it's not being used (these systems have been around since CF4.5). something I'll follow up here. thanx b On 9/20/06, Brent Nicholas <[EMAIL PROTECTED]> wrote:
I hate answering with "I thinks.." but I do recall in the Advanced CF Book for CF4.5 it had write up's on cluster cats in it for load balancing, I recall it talked about different techniques for making sessions portable.
