I need to build a scalable webserver based on Apache. I'm not sure yet if the application requires persistent TCP connections. If so, it will require that after starting session all subsequent HTTP request in this session will come to the same machine in the cluster. This requires load ballancing in 7th layer, so LVS doesn't help much.
The question is: are there any software level 7 ballancer available ? If not, which hardware box would you recommend ? -=Czaj-nick=-
