Method for information exchange in the customer/server mode between stations connected by a communication network
First Claim
1. A method for information exchange in the client-server mode between stations connected by a communication network, in which:
- a network is formed by a communication hub and a plurality of stations each associated with a coupler on the hub,at least one server station is arranged on the network,each coupler is provided with a network communication protocol, allowing the processing of requests (REQ) for consulting a resource file (Fi) between client stations and the server station,wherein said method comprises the following steps;
at at least one client station,maintaining locally an auxiliary file representing a correspondence between a designation of the resource file, a substitute location (ESi) for the resource file, and a condition key for use by the substitute location (ESi),providing an emulated server (SEM) to communicate according to the protocol for processing requests for consulting a resource file at the initiative of the emulated server,at a coupler between the at least one client station and the network, providing a mechanism (INT) for intercepting a request for consulting the resource file, by redirecting the request to the local emulated server (SEM),at the emulated server (SEM), accessing the auxiliary file and receiving an intercepted request; and
if the condition key for the requested resource file is correct, processing the request with the substitute location (ESi), and, if not, directing to the server station a derived request to obtain access to the requested resource file.

Abstract
A method for information exchange in the customer/server mode between stations connected by a communication network is described. An emulated server (SEM) is provided at at least certain stations. The emulated server is appropriate for dialog according to a communication protocol to process requests for consulting resource files at a coupler between a station and the network. An interception mechanism (INT) is used to intercept the requests for consulting the resource files by redirecting them to the local emulated server. The emulated server is used either as a cache memory to reduce traffic or as a switch to mitigate and remedy a breakdown of the server.
