that requires an application-level firewall. think of a keepalive HTTP request.
the items sent back are the following: the html page, 3 images, an mp3 music theme for
the site, 5 flash animations, and a pdf at last.
there are multiple contencts in a single connection. even a single tcp packet could
share two or more type of contents.
think of it...

pf itself is a packet-level firewall. any application-level extensions are in the
userland, like the ftp-proxy.
