Remarks

If the user needs to connect to a remote server through a proxy, this property should be set to a value other than ProxyNone. Depending on the type of remote proxy, the user should specify the correct protocol with this property. The most common proxy type is ProxyFTPUser. Socks 4/4a and Socks 5 are general proxy protocols, universal to any type of protocol. Relay is not a real proxy, but just a 'pipe' or 'redirector' that listens on a predefined port, and when a client connects to it, opens a predefined destination hostname and redirects all traffic between the client and the remote server. A relay proxy is very useful when testing other protocols.

ProxyWindows type is included in version 2.5.1. It uses same values as specified in Internet Explorer, under Tools->Internet Options->Connections->LAN Settings. wodFtpDLX will use anything specified for "Socks", or for "FTP" if socks isn't specified.

ProxyFTPUser, ProxyFTPOpen and ProxyFTPSite are available only for FTP protocol - since they initiate regular FTP connection and expect to connect 'ftp alike' proxy server. Then, instead of sending 'USER joe' command, wodFtpDLX sends similar command 'USER joe@real.ftp.server' so that proxy can relay connection to appropriate destination. In the same way, instead of 'USER joe@real.ftp.server', wodFtpDLX can send 'OPEN real.ftp.server' or 'SITE real.ftp.server', depending on your ProxyType property selection.
