Yes, understood :)

Yes, to both.

web.xml is at: https://github.com/arun-gupta/wildfly-samples/blob/master/clustering/http/src/main/webapp/WEB-INF/web.xml

This WAR file shows sessions being replicated when two instances are
created on the same host in other-server-group which points to full-ha
profile. In both cases (instances on same host or instances as
master/slave), the app is deployed to other-server-group. Does
anything need to be explicitly configured for session replication when
instances are on separate hosts ?

FWIW I've been using port hopping to show session replication, without
any LB in the front. Does that matter ?
