Abstract

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 determined that the request should be processed in the first network server. On the other hand, the request is routed to another network server in a case that it is determined that the request should not be processed in the first network server.
