  • Patent number: 6349336
    Abstract: The invention enables a tunneling action that allows a remote processor to communicate with a local processor when the remote processor is coupled to the local processor via a reverse proxy device, a computer network, a firewall and a proxy agent device. Initially, the local processor establishes a communication channel with the remote processor by dispatching a local request message to the proxy agent device. The proxy agent device dispatches the local request message via the firewall and network to the reverse proxy device, thus enabling the firewall to receive a remote response message to the local request message. Thereafter, the remote processor issues a remote request message to the reverse proxy device, which in turn dispatches a remote response message with the remote request message contained therein, to the firewall.
