#  Note: Your FTP Proxy server may or may not require authentication.

#  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.
