Chapter 4: HTTP Tunneling

4-2

HTTP Data Communication Using HTTP Tunneling

In HTTP tunneling, data communication using the HTTP protocol can be conducted by converting data

communication with the IIOP protocol used usually in CORBA applications into HTTP data. This is a

useful function when you want to establish client-server linkage beyond the firewall.

HTTP Tunneling Mechanism

The following shows the HTTP tunneling mechanism:

On the client side, when HTTP tunneling is specified at start of the client application a request is sent as

HTTP data during request sending from the client to the server.

On the server side, the following must be constructed: A Web server for receiving the HTTP data and

HTTP gateway environment for converting HTTP data to IIOP data. A request sent to the server is

converted from HTTP to IIOP data via the Web server and HTTP gateway environment. The server

application (CORBA application) can receive the request as the IIOP data.

Figure 4-1 shows a processing image of the HTTP tunneling.
