                In a production environment, a load balancer or Web proxy server is used to distribute client connection requests, provide load balancing and failover across the cluster, and provide security by concealing the local area network addresses from external users. A load balancer or Web proxy server allows all applications in the domain to be represented as a single address to external clients, and is required when using in-memory replication for client session information.
