Session management

 

One of the other functions that the plug-in provides, in addition to failover and workload management, is the ability to manage session affinity.

HTTP sessions allow applications to maintain state information across multiple user visits. The Java servlet specification provides a mechanism for applications to maintain all session information at the server and exchange minimal information with a user's browser.

The methods used to manage the sessions are very important in a workload-managed environment. There are different methods of identifying, maintaining affinity, and persisting the sessions.

See HTTP sessions and the session management facility for basic information or Chapter 14, "Configuring session management", of the redbook IBM WebSphere Version 5.0 System Management and Configuration, SG24-6195 for details on this subject.
