Http (since 1.1, forever) has a Keep-Alive option that reuses the
connection to fetch file after file.

Ftp opens one control connection for the whole session and then
initiates one data connection per file. Depending on active or passive
ftp that connection comes from the client or server. Firewalls often
don't like that. Under linux you need the ip_contrack_ftp and
ip_nat_ftp modules to handle those.
