But I thought the squid-like http proxy while serving the FTP URLs is what the
ftp proxy is? It's a different matter at least because it's a nothing about
HTTP's CONNECT method.

Can you point me to a definition of 'ftp proxy' please? Wikipedia and Google
have nothing on this.

What I described is mentioned as 'http tunneling' in delegate's docs and isn't
specific for ftp at all.

Management is always the same on both sides of Earth, right.
