Chapter 5: New Features in EAServer Versions 4.2.3, 4.2.2, 4.2.1, and 4.2

In-memory HTTP session replication

For Web applications that are deployed in an EAServer cluster, EAServer 4.2 can distribute HTTP session data using in-memory replication rather than database storage. This feature can improve performance by avoiding the overhead of writing to the database. For more information, see “Deploying Web applications to a cluster” in Chapter 7, “Load Balancing, Failover, and Component Availability,” in the EAServer System Administration Guide.
