Answer» Session replication between multiple cluster nodes can be done in MANY ways. The best approach may depend on the type of application. However there are few common methods USED by application server vendors. Using session persistence, and saving the session to a shared file system (PersistenceManager + FileStore) . This will allow all machines in a cluster to be ABLE to access the persisted session from the shared file system. Using session persistence, and saving the session to a shared database (PersistenceManager + JDBCStore) - This will allow all machines in a cluster to be able to access the persisted session from the shared database system. Using in-memory-replication, This will create a in memory COPY of session in all the cluster nodes.
