Abstract
Computer implemented methods () for protecting web based applications () from Cross Site Request Forgery (CSRF) attacks. The methods involve () classifying each resource offered by a web server application as a CSRF-protected resource or a not-CSRF-protected resource. The methods also involve () performing a user authentication, () initializing an authentication-token, and () initializing a CSRF protection secret that is used to validate CSRF protection parameters contained in resource identifiers for the resources. The methods further involve () performing a server-side rewriting process () to add the CSRF protection parameter to the resource identifiers for the resources and/or () performing a client-side rewriting process to add the CSRF protection parameter to a resource identifier for a second resource (e.g., a resource created at a client computer ()).
