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