Replicated front-end WebSEAL servers

Junction support for back-end servers starts with at least one front-end WebSEAL server. Replicated front-end WebSEAL servers provide the site with load balancing during periods of heavy demand. The load balancing process is handled by a third-party device such as Cisco Local Director. Front-end replication also provides the site with failover capability. If a server fails for some reason, the remaining replica servers continue to provide access to the site. Successful load balancing and failover capability results in high availability for users of the site. When we replicate front-end WebSEAL servers, each server must contain an exact copy of the web space and the junction database. Account information for authentication is in a user registry that is independent of the front-end servers.
