i have some question regarding session replication in a clustered environment..

i am doing a poc on session replication in a clustered environment session replication happens ? a two server cluster server 1 and server2
when server 1 is down all its session is replicated to server 2 which is active..
is the replicated session comes back when the server 1 is active again? there any way we can find out which server currently serves the request for information purpose?

Hi Samal,

Using in-memory replication, WebLogic Server copies a session state from one server instance to another. The primary server creates a primary session state on the server to which the client first connects, and a secondary replica on another WebLogic Server instance in the cluster. The replica is kept up-to-date so that it may be used if the server that hosts the servlet fails.

(from docs)

ALso the flow chart at the end gives you good idea of Failover with proxy plug-in
