METHOD AND SYSTEM FOR STATELESS VALIDATION

A method of validating parameters of a request from a Web client to a Web application. The validation rules are sent to a Web client, together with a response to a Web client. The parameters in a response are updated by the Web client. The updated parameters are sent in a subsequent request to the Web client, along with the validation rules. The updated parameters are validated using the validation rules in the request, thus achieving stateless validation. The validation rules are preferably digitally signed.
