I have attempted this and spent much time hacking away also hopeing to
do what trend claims to do but alas this is only a claim the big problem
is that the scanner does not pass traffic back to the browser until the
file is scanned this is where the wheels fall off as there is a
potential for a browser timeout while it waits for the download to
complete and scan it before passing it on to the client ...

squid is a bit more complicated as it buffers the data and writes it to
disk and the client almost simultaneously from a circular buffer [this
gives squid its speed] now to scan a file you will not buffer to the
client and only once the cache FD is closed scan it and pass it on to
the client ie write scan then pass to client this will break the speed
and efficincy of squid also why would you want to scan .gif/.jpg/.html
but then again prehaps a bug is hidden in this file with a iframe /
object tag executeing it ... 

this will force you to scan every file the lag will be great but worse
when downloading a ISO [yeah ppl use a browser for this] you will almost
be certain it will fail as it does with trend ... unless you are able to
download it in under 5 mins ... 

i have given up doing this i have had it working at one stage but have
turned my back on it ... in the past all my trend customers turned there
web scanning off due to these problems ...
