Abstract: A method for simulating the operation of devices having a predetermined architecture relative to devices that may have a different architecture, includes the following steps: transmission by a user client connected to a computer network of a request to a server, the purpose of the request being to access a predetermined application contained in the server; transfer from the server to the user client of the corresponding client module with the automatic integration thereof into the network browser; setting up of the client module and transmission of a request by the client module in order to obtain the transfer from the server to the user client of a portion at least of the information, data and resources included in the corresponding content file; setting up of an emulation node contained in the client module; integration of the data or resources previously transferred into the emulation node; automatic execution of the predetermined application.
