/**
 * A simple, tiny, nicely embeddable HTTP 1.0 (partially 1.1) server in Java

 * (elonen@iki.fi, http://iki.fi/elonen/) and Copyright &copy; 2010 Konstantinos
 * Togias (info@ktogias.gr, http://ktogias.gr)
 *
 * <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 (+ rudimentary PUT
 * support in 1.25)</li>
 * <li>Supports both dynamic content and file serving</li>
 * <li>Supports file upload (since version 1.2, 2010)</li>
 * <li>Supports partial content (streaming)</li>
 * <li>Supports ETags</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 supports partial content (streaming)</li>
 * <li>File server supports ETags</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 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 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>
