Echo Pipe (HttpPipe Example)

The Echo Pipe is a simple example that shows how to use the HttpPipe. The HttpPipe comes bundled with the EventHandler plugin.

The Echo Pipe server echoes back data sent from the client. The client is a simple command line Java program that sends any text typed using the keyboard to the server.

The HttpPipe is used as a regular TCP socket connection, but is tunneled on top of HTTPS. Applications using the HttpPipe can use the authentication and authorization built into the server. Applications built on top of the HttpPipe can be used, for example, to tunnel traffic out from behind a restrictive firewall/proxy that only allows outgoing HTTPS web connections.

The Echo Pipe consists of a Java client and a resource installed at location '/echo.pipe' in the server. The resource, which is an instance of an HttpPage object, dynamically creates new HttpPipe instances when clients connect to the server resource '/echo.pipe'.

Running the Example:

Compile and run the server.

Compile and run the Java client program.

• Windows users: Run the batch file in the Java subdirectory.
• UNIX users: copy the content of the batch file to a UNIX script and run the script.
• Run the Java program from the DOS/console: java -jar echo.jar
