System and method for managing web applications

A method, system and article of manufacture for processing requests in web applications and, more particularly, for processing requests between two different applications. One embodiment provides a computer-implemented method of processing a copy request in a distributed environment including at least a first and a second application. The method comprises receiving, from the first application, a copy request for a copy of a selected object. A fully defined instance of the selected object resides in the second application and only a representation of the fully defined instance resides in the first application. The method further comprises generating, by the second application, an object descriptor representing the fully defined instance. At least a portion of the fully defined instance is excluded in the object descriptor. The object descriptor is transmitted from the second to the first application. Thereby, access by the first application to the fully defined instance is prevented.
