 * HtpServer implements a very simple HTTP server. This server can be
 * used as a free-standing HTTP server for URL requests. It can also
 * be used in a more complex application to serve files. For example,
 * this can be used to serve files in response to a request made through
 * a speech agent (e.g. a spoken request "Where is Elm Street?" can be
 * handled with a display of the map.)
