L4 loadbalancer for virtual hosts

[John D.]

Hello,

Do you know how to make a Layer 4 load balancer (for example, LVS), 
support the virtual hosts (for instance, the http host header)?

I ask this b/c our application are the socket servers (game servers). 
They have a special socket port, it can be bound on LVS server. Behind 
LVS there are many servers for different partitions. So we want to make 
LVS balance the requests to the different partition based on some tags, 
for example, the http header.

Thanks.
