Do you mean a HTTP proxy server, such as Squid? There is a filter plugin
for Squid and a new "squid-vscan" project that is supposed to scan
content on-access using a virusscanner.

I haven't tried it out yet; there is no FreeBSD port yet but good chance
it will run. http://www.openantivirus.org/projects.php

I would assume that scanning every incoming file will use your available
system resources quickly. As long as browsers are broken and ignore the
Content-Type you will have to fire up the virusscanner for *every* cache
miss; if you have many people behind the proxy you will probably need
fast disks and probably even multiple proxies.

I don't have plans for such a setup currently, but it seems like an
interesting task. Let me know what solution worked out for you and what
your comments are about its performance!
