5.2 Overview of the session failover functionality
The session failover functionality inherits objects registered in the HttpSession object on a J2EE server when a software failure, hardware failure, or network failure occurs on a J2EE sever or a Web server.
If you use the session failover functionality and if a failure occurs on a specific J2EE server in a system, you can continue the operations on another J2EE server by inheriting session information before failure. Thus, you can improve the availability of the system.
The following subsections describe the benefits of using the session failover functionality and the types of functionality.
