Well, any decent load balancer would be able to load balance at both ends.

It is my understanding that if I have a group of servers running IIS, and a separate group of clustered servers running CF, then I have load balancing going on at two different levels. The first level is between the user and IIS, and the second level is between IIS and my CF Instances. My Hardware load balancer only sits between the user and the servers running IIS. Keep in mind CF might not even be installed on those servers. Now once IIS gets the request from the hardware load balancer, the web server connector uses my cluster algorithm (Let's say Round Robin) to choose an instance in the cluster (assuming it is not static content being served). At this point the hardware load balancer is out of the picture. It is also at this point that I want my balancing to be based on things like CPU. >From what people are telling me though, the IIS connectors aren't smart enough to do that. ~Brad ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Create Web Applications With ColdFusion MX7 & Flex 2.
