Abstract: The present invention relates to a method for automatic browsing from a web browser over a plurality of web pages which are stored on servers so that all the data flows between the browser and the servers of the web pages pass via an interposition server, including steps for: creating and storing at least one scenario for automatic browsing having a web page address for launching the scenario and at least one web page address for redirection, selecting the automatic browsing scenario including the launch address which corresponds to the address of a request transmitted by the web browser, intercepting the response of the host server to the request for access with the interposition server, modifying the response into a redirection response including the redirection address defined in the scenario, generating a request by the browser to access the redirection web page.
