Abstract

A system and method of proxying communications over a complex network (112). One embodiment of the invention comprises a first (104) and second process (108) that communicate over a complex network environment. A first proxy (120) transparently intercepts communications from the first process (104) to the second process (108) and transmits the intercepted communication to a second proxy (124). The second proxy (124) then forwards the intercepted communication to the second process (108). The first proxy (104) and the second proxy (108) can package the intercepted communications for transmission across a complex network environment (112). Since the communications are transparently intercepted, the first process (104) and the second process (108) can communicate over complex network environments, such as a firewall, without requiring intimate knowledge of such environment.
