/**
* A simple, tiny, nicely embeddable HTTP 1.0 server in Java
*
* <p>
* NanoHTTPD version 1.14, Copyright © 2001,2005-2010 Jarno Elonen
* (elonen@iki.fi, http://iki.fi/elonen/)
*
* <p>
* <b>Features + limitations: </b>
* <ul>
*
* <li>Only one Java file</li>
* <li>Java 1.1 compatible</li>
* <li>Released as open source, Modified BSD licence</li>
* <li>No fixed config files, logging, authorization etc. (Implement yourself if
* you need them.)</li>
* <li>Supports parameter parsing of GET and POST methods</li>
* <li>Supports both dynamic content and file serving</li>
* <li>Never caches anything</li>
* <li>Doesn't limit bandwidth, request time or simultaneous connections</li>
* <li>Default code serves files and shows all HTTP parameters and headers</li>
* <li>File server supports directory listing, index.html and index.htm</li>
* <li>File server does the 301 redirection trick for directories without '/'</li>
* <li>File server supports simple skipping for files (continue download)</li>
* <li>File server uses current directory as a web root</li>
* <li>File server serves also very long files without memory overhead</li>
* <li>Contains a built-in list of most common mime types</li>
* <li>All header names are converted lowercase so they don't vary between
* browsers/clients</li>
*
* </ul>
*
* <p>
* <b>Ways to use: </b>
* <ul>
*
* <li>Run as a standalone app, serves files from current directory and shows
* requests</li>
* <li>Subclass serve() and embed to your own program</li>
* <li>Call serveFile() from serve() with your own base directory</li>
*
* </ul>
*
* See the end of the source file for distribution license (Modified BSD
