31 * (<b>Entry point</b>) Demonstrates how to write a very simple tunneling proxy
32 * using MINA. The proxy only logs all data passing through it. This is only
33 * suitable for text based protocols since received data will be converted into
34 * strings before being logged.
35 * <p>
36 * Start a proxy like this:<br>
37 * <code>org.apache.mina.example.proxy.Main 12345 www.google.com 80</code><br>
38 * and open <a href="http://localhost:12345">http://localhost:12345</a> in a
39 * browser window.
