Hi all.
Is it possible to cluster orion (2 servers with one instance each) without
using loadbalancer.jar? I have a hardware loadbalaner which handles the

I thought the primary reason for clustering was to be able to provide

So does it mean we need any other layer of load-balancing failover, like
at the Web Server farm?
