Configure geronimo to act behind a load balancer

we are currently preparing our application for production use. One topic ist
load balancing. The proposed architecture is:

1.) one load balancer (apache mod_jk)
2.) two geronimo nodes (2.1.4) behind mod_jk

The configuration is derived from the apache http dialog in Geronimo console
application. The communication works, but faces dialogs dont' work. The
reason is that the load balancer switches between the nodes. So faces does
not find a view on incoming requests from jsf pages. 

Any hints how this situation should be configured. Will it be necessary to
activate session replication? (at the moment it's not activated)

Software oveview:
Operationg System: ubuntu
Apache web server: Apache 2.2.11-2ubuntu2.6,
Apache mod_jk: mod_jk 1.2.26
Application Server: Geronimo 2.1.4 with tomcat web server.

thanks in advance,
Ralf

Sounds like sticky sessions aren't configured properly.
