URL url = new URL(urlString);

int port = url.getPort ();

if (port == -1)
{

}

socket = new Socket(url.getHost (), port);

out = socket.getOutputStream ();
InputStream in = socket.getInputStream();

Writer writer = new OutputStreamWriter (out, "ISO-8859-1");

writer.write ("POST " + url.getFile () + " HTTP/1.0\r\n");

}
catch (ClassNotFoundException nf)
