SquiVi2 is a redirector for squid. It makes is possible to include an virusscanner
in squid to search for viruses and trojans in the requested files. You can include
as many virus scanners and compression tools as you want.
Also you will find other usefull tools and extensions for squid on this site.
There is still more to come... A interface for scanning in SSL transfers will be
the next. Mail me if you want other things!
