I am adding the following cluster element to <engine> for vertical
cluster and to <host> for horizontal cluster for development.
I started configuring mod_proxy_ajp and have some problem to configure,
so I may post another question later.
Anyway, for vertical cluster, we have setup DNS round robbing for load
balancing. When we shutdown one node, a user is routed to anther node,
but tomcat asks a user to re-login.
For horizontal cluster, at least tomcat does not ask re-login to access
a different node running on the same host, but I would like to setup
load balancing.

How are you configuring the cluster in each case?
What have you tried?
