Hi, thanks for your answer.
I've checked the howto's using Pound and HAProxy already and they really usefull.
But actually, what i ment was that if it is possible to build the same type of cluster (2 LoadBalancer in Active/Pasive and RealServers in Active/Active), let's say in Gutsy Gibon, using just heartbeat + ldirectord and LVS/ipvsadm and not ultramonkey.
So that way i wont just only be able to have apache clusters and instead build clusters for other services using the same scheme, without ultramonkey.
thanks for help.
