Arno Unkrig commented on NET-508:
---------------------------------

The "KERNUN FTP Proxy" proxy server seems to support

(4) USER pu@u@ftp.acme.com PASS pp@p

, see

http://download.kernun.com/doc/handbook/adv_auth.html

Does it also accept some of the other schemes (1, 2, 3)?

> The COMMONS-NET FTP client supports 'FTP over HTTP', but not the other popular FTP proxy schemes. The article
>  http://www.codeproject.com/Articles/9547/How-Proxy-Server-serves-FTP-clients
> describes some of them, but not very precisely an obviously a bit incorrect.
> I added proxy support for the ANT FTP task in
>  https://svn.code.sf.net/p/loggifier/code/trunk/ant_issue_54883/src/org/apache/tools/ant/taskdefs/optional/net2/FTP2.java
> (search for string "proxyServer"), but I believe that the feature should be implemented in COMMONS-NET, not in the application, maybe like this:
>  connectToProxyAndLogin(server, port, userid, password, proxyServer, proxyPort, proxyUserid, proxyPassword)
> The proxy server that I (must) use is
>  220 McAfee Web Gateway 7.2.0 build 13935
> , and from experiments it supports the following authentication schemes:
>  (1) USER pu PASS pp OPEN ftp.acme.com USER u              PASS p
>  (2) USER pu PASS pp                   USER u@ftp.acme.com PASS p
>  (3) USER pu PASS pp SITE ftp.acme.com USER u              PASS p
> I don't know which FTP proxy servers support which of these flavors, but (2) appears to be the most natural and robust to me.
