public class EchoServer

extends NetworkServer

A simple HTTP server that generates a Web page showing all of the data that it received from the Web client (usually a browser). To use this, start it on the system of your choice, supplying a port number if you want something other than port 8088. Call this system server.com. Next, start a Web browser on the same or a different system, and connect to http://server.com:8088/whatever. The resultant Web page will show the data that your browser sent. For debugging in servlet or CGI programming, specify http://server.com:8088/whatever as the ACTION of your HTML form. You can send GET or POST data; either way, the resultant page will show what your browser sent.
