public class UDPRedirector
extends ClackApplication

A Clack application that uses a Clack host to proxy to a real Internet host, thus redirecting the UDP traffic.

The redirect effect is achieved using two sockets. One is a socket running on the clack router and another is a real Java socket connected to the host that the redirector is proxying. Any data received in the Clack socket is sent to the real host using the Java socket, and any data received using the java socket is sent back to the client using the Clack socket. This effectively allows us to pretend like a real-host is inside our Clack network.
