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