Abstract: A method, apparatus, and manufacture for content protection for protecting some objects is provided. A content protection operation or license operation is performed for at least one media object of a web application. Some or all of the objects are then marked as protected. When an operation is performed that accesses a protected object, a user agent determines whether to deny the operation, to allow the operation and mark data exported by the operation and objects storing the exported data as protected objects, or to allow the operation and not mark data exported by the operation and objects storing the exported data as protected objects.
