Patent ID: 7401114

Claim:
A method of making a computational service available in a multiple server computing environment comprising: exchanging information between a plurality of servers; initiating a connection between a client unit and a first server of said plurality of servers; determining a most recently accessed session of a plurality of sessions on said plurality of servers; determining at said first server a location of said most recently accessed session on one of said plurality of servers; and redirecting said client unit via said first server to a second server of said plurality of servers having said most recently accessed session; wherein each of said plurality of sessions comprises a plurality of services requested by said client unit; wherein said first and second servers can each provide said plurality of services; wherein said plurality of services comprise state maintenances for a user of said client unit; wherein redirecting is executed when said first server fails to respond to said client unit with a message, the message indicating availability of said first server, and said redirecting of said client unit to said second server maintains access to said accessed session while continuing said plurality of services to said client unit so as to eliminate a single point failure.
