ABSTRACT:
A remote session server, or bank of remote session servers, is provided to a bank of web servers. Each web server maintains a cache that contains all of the session information for all sessions being serviced by that server. The web server utilizes its local cache to perform all session services. The remote session server maintains a copy of all session information from all caches, and is updated whenever changes are made on each web server. If a web server should go down, an ongoing session can be transferred to a different web server. In such event, the new web server is able to obtain the previous status of the session from the remote web server and continues serving the session in a transparent manner.
