ok, after reading the lists it is becoming apparent that the Orion loadbalancer is not the best thing to be using. Mainly because i need the clients ip address for a form of authentication, and the loadbalancer.jar wont give it to my orions back ends. Therefore, can anyone suggest a resaonably priced hardware/software load balancer which i could use for my Orion clustering. Any reviews anywhere of load balancers? I would prefer suggestions/something which is straight forward rather than hacking things like Apache. Cheers Darren
