Abstract: The invention relates to a method for processing HTTP requests and HTML pages transmitted or received by a navigator to or from at least one Web server such that all of the data-flows between the navigator and each Web server pass via an interposition server (P), comprising the steps of: storing (2) a list of configuration parameters defining data to be selected from the data-flows between the navigator and each Web server; acquiring (4) data to be selected by filtering the HTTP requests and HTML pages passing via the interposition server; selecting (4) forms contained in the data-flows and containing at least one entry field corresponding to at least one configuration parameter, and modifying (6) the or each entry field found by adding a default value corresponding to one of the previously acquired data.
