    // The ProxyMethod should be an integer value between 1 and 5.
    // If you know your FTP proxy server's authentication scheme,
    // you may set it directly.  To determine the ProxyMethod,
    // call DetermineProxyMethod.  A return value of -1 indicates a failure.
    // A return value of 0 indicates that nothing worked.
    // A return value of 1-5 indicates the ProxyMethod that was 
    // successful, and this should be the value used for the ProxyMethod
    // property.
