Abstract:
A method for providing invisibility to a compulsory gateway of an IP network, the gateway comprising a proxy-server, the proxy-server including a plurality of individual servers and an inverse load balancer, said method comprising the steps of:a) receiving at one individual server of said plurality of individual servers of said proxy-server, a request from a user, said request comprising a user identifier identifying said user as the source of the request and a remote content server identifier identifying a remote content server as the target of the request; b) creating a cross reference of said user identifier and an individual server identifier identifying said one individual server, said cross reference for use by said inverse load balancer for directing responses from remote content servers to a requesting individual server of said plurality of individual servers of said proxy-server; and, c) directing said request to said remote content-server when said request cannot be served by said proxy-server, said directed request comprising said user identifier as the source of the request rather than said individual server identifier whereby said one individual server is invisible to said user and said remote content-server.
