Abstract

In response to a request transmitted by a client through the Fire Wall, a unique service server provides a unique service to the client by using a communication port. Response to an HTTP request which is not directed to the unique service, the unique service server transfers the request to the WWW server without processing, it provides both services by one communication port. A request for acquiring a data service is sent by a client HTTP through the Fire Wall, the unique service server determines the client'"'"'s request is directed to data provided by the WWW server or directed to the uniquely provided data. If the unique service server determines that the client request is directed to the uniquely provided data, the processing is executed. If the unique service server determines that the client request is directed to data provided by the generally used WWW server, the server transfers the request to the WWW server.

Claims

1. A data processing apparatus for supplying a client in a network with data other than data provided by a server, in conformity with a generally used protocol, comprising:

determination means for determining whether a given request from a client is directed to data supplied by the server or directed to data uniquely supplied by said data processing apparatus; and
