If ProxyLogin and
ProxyPassword properties are set, wodFtpDLX will try to
send these credentials to proxy server before it sends
command to finally select destination FTP through proxy. It
uses regular 'USER' and 'PASS' commands to
supply this information.
Besides ProxyFTPUser,
ProxyFTPSite and ProxyFTPOpen, only the Socks
5 protocol supports passwords when connecting to a
proxy server. For other proxy types, this property is
ignored.
