I am trying to configure a load balancer (round robin) in front of multiple instances of GeoServer. The OGC services work just fine but the web GUI gets into an infinite redirect loop and fails to load in the browser. I could try setting up a JDBC session manager in Jetty but I believe Apache Wicket is doing some in memory session management that will subvert this.
The topic is discussed here:
Would someone with more experience with Wicket comment on this?
