com.hazelcast.web.ClusteredSessionService

public class ClusteredSessionService
extends Object

ClusteredSessionService is a proxy class which delegates all operations on distributed map to hazelcast cluster used for session replication. ClusteredSessionService is also responsible for safety of the cluster connection. If a map operation fails due to network issued, a background thread always retries connection and ensures the safety of connection.
