<p>
        Public method to connect to the given FTP server.
</p><p>
        This extended method connects to the proxy instead of the given host,
        if a proxy is to be used. It throws an exception, if the proxy data
        is incomplete.

        Public method to login to the FTP server.

        This extended method respects the FTP proxy configuration. There are
        many different FTP proxy products available. But unfortunately there
        is no standard for how o traverse a FTP proxy. The lis below shows
        the sequence of commands used.

<h2>E5FtpProxyError</h2>
<p>
    Class to signal an error related to proxy configuration.
</p><p>
    The error message starts with a three digit error code followed by a
    space and the error string. Supported error codes are:
    <ul>
      <li>910: proxy error; the second number gives the category of the proxy
          error. The original response from the proxy is appended in the next
          line.</li>
      <li>930: proxy error; the second number gives the category of the proxy
          error. The original response from the proxy is appended in the next
          line.</li>
      <li>940: proxy error; the second number gives the category of the proxy
          error. The original response from the proxy is appended in the next
          line.</li>
      <li>950: proxy error; the second number gives the category of the proxy
          error. The original response from the proxy is appended in the next
          line.</li>
      <li>990: proxy usage is enabled but no proxy host given</li>
      <li>991: proxy usage is enabled but no proxy user given</li>
      <li>992: proxy usage is enabled but no proxy password given</li>
