   URL                 url;
   URLConnection   urlConn;
   DataOutputStream    printout;
   DataInputStream     input;
   // URL of CGI-Bin script.
   url = new URL (getCodeBase().toString() + "env.tcgi");
   // URL connection channel.
   urlConn = url.openConnection();
   // Let the run-time system (RTS) know that we want input.
   urlConn.setDoInput (true);
   // Let the RTS know that we want to do output.
   urlConn.setDoOutput (true);
   // No caching, we want the real thing.
   urlConn.setUseCaches (false);
   // Specify the content type.
   urlConn.setRequestProperty
   ("Content-Type", "application/x-www-form-urlencoded");
   // Send POST output.
   printout = new DataOutputStream (urlConn.getOutputStream ());
   String content =
   "name=" + URLEncoder.encode ("Buford Early") +
   "&email=" + URLEncoder.encode ("buford@known-space.com");
   printout.writeBytes (content);
   printout.flush ();
   printout.close ();
   // Get response data.
   input = new DataInputStream (urlConn.getInputStream ());
   String str;
   while (null != ((str = input.readLine())))
   {
   System.out.println (str);
   textArea.appendText (str + "\n");
   }
   input.close ();
