Indeed. I don't think FTPS through a HTTP proxy is working. It is funny how
you posted about this only minutes after someone else posted a very similar
mail on the libcurl list: http://curl.haxx.se/mail/lib-2006-09/0097.html

So yes, it will need a fix. I don't think Marcos' fix (in that URL) is really
working though so it might need something more, but I'm of course interested
in getting to know the results.

Possibly you could perhaps get together and try working out something.
