ABSTRACT:
The present invention provides a system and method for distributing load among redundant, independent, stateful web server sites that overcome the limitations of prior art solutions. This is accomplished by constructing the server computer to respond to an initial connection request from a client computer with the name of a server computer site, pool or group selected based on various criteria. The server computer site, pool and group names are maintained in DNS nameservers with load balancing and failover capabilities. As a result, the single-point-of-failure and performance issues introduced by prior art web proxy servers are eliminated. In addition, since the session state information is only maintained on the selected server computer site, the need to synchronize web proxy server state with server computer state is eliminated.
