Kevin M O Neil, Robert F Nerz, Robert R Aubin: System for balancing loads among network servers. Web Balance, David J Powsner, Nutter McClennen & Fish, October 3, 2000: US06128279 (421 worldwide citation)

A system which distributes requests among a plurality of network servers receives a request from a remote source at a first one of the network servers, and determines whether to process the request in the first network server. The request is processed in the first network server in a case that it is ...
