proxy - Proxies in Python FTP application

Question

I'm developing an FTP client in Python ftplib. How do I add proxies support to it (most FTP apps I have seen seem to have it)? I'm especially thinking about SOCKS proxies, but also other types... FTP, HTTP (is it even possible to use HTTP proxies with FTP program?)

Any ideas how to do it?

As per this source.

Depends on the proxy, but a common method is to ftp to the proxy, then use the username and password for the destination server.

E.g. for ftp.example.com:

Server address: proxyserver (or open proxyserver from with ftp)
User:           anonymous@ftp.example.com
Password:       password

In Python code:

from ftplib import FTP
site = FTP('my_proxy')
site.set_debuglevel(1)
msg = site.login('anonymous@ftp.example.com', 'password')
site.cwd('/pub')
