Load balancers that use session affinity dynamically select the best-performing server to when establishing a session. The load balancers send subsequent requests for the same session back to the same server.
Configuring session affinity helps your load balancers operate more efficiently because the CA SiteMinder caches are used to their full potential. For example, sessions are stored in the Web Agent cache when they are created. Since the session is cached, subsequent requests for resources during the same session are validated using the information from the Web Agent cache. The Policy Server is not contacted, and efficiency is increased.
