Options for handling session failover events

Advanced Access Control offers several solutions to the challenge of providing sharing of session state across multiple servers in a clustered environment. The following sections describe the options available for handling failover events in clustered environments:

• No handling of failover events
• The Distributed Session Cache

• Option 1: No handling of failover events
  Failover events are rare when WebSEAL or web reverse proxy instance is configured to maintain session affinity in a stateful junction to Advanced Access Control.
• Option 2: The distributed session cache
  The distributed session cache (DSC) can be used for session storage by all ISAM appliances in a cluster.
