Re: Load Balancers

Keep the load balancer. The issue for you, I think, is
how you replicate your HTTPSessions across the members
of the cluster.

This is most likely determined by the web/app server
you are using. The container that holds the state will
most likely have a defined way to replicate session
data, either by writing it to a common database or
using UDP to multicast data across the cluster.

Here is an interesting article on how this is done in
Tomcat 5:
