  • Tunneling apparatus and method for client-server communication
    Patent number: 8954590
    Abstract: An HTTP tunneling service is described for creating a tunneled path between a client and a server (e.g., over a firewall or other data/protocol filtering device). According to one embodiment of the invention the client sends the server an initial request to open a preliminary socket connection which includes a secure client ID previously assigned to the client. The server opens the preliminary socket connection, generates a random client ID and transmits the random client ID to the client. The preliminary socket connection is then closed. The client then sends a second request to open a second socket connection using both the unique ID and the secure client ID for authentication purposes.
