They probably have many servers and proxies.... so you shouldn't consider that
the name->addr relation is a simple one.

the browser uses http protocol to connect to the proxy, and the latter uses
ftp to
connect to the server. it knows it's ftp from the URL as it receives
something like:
GET ftp://ftp.site.example/purple/haze HTTP/1.0

by default, the browser sends "anonymous" (or another configurable name) as
the username
and email address as the password. it acts as if doing anonymous ftp.
if you want to ftp with your userid, use a URL like:
ftp:[EMAIL PROTECTED]/mydir/anotherone/file.txt
then you'll be prompted for a password.
you can pass the passwd directly using:
ftp://username:[EMAIL PROTECTED]/whatever/you/want
but you need to watch for bad guys behind the shoulders....
