Sure, I know of some load balancing software, but I do not know of any
that support sticky sessions out of the box.
BTW, how are these sessions passed? Is this a client-server approach,
where the LB accepts the session data and uses a proxy to forward them
to the load balanced machine, or does the load balancer do it's thing at
perhaps Layer 2, and completely forwards the connection to the LB'd server?
Thanks!
