Antispyd is an HTTP/HTTPS threat filtering proxy
server. The main characteristic of this project is
the modularity of his conception. The program is
organized around an HTTP/HTTPS gateway service and
a set of filters that can be enabled or disabled,
and are all configurable with a single
configuration file. Current filters are: URL
filtering, content filtering, content-type
filtering, cookie removal, pop-up removal, shell
code attack blocking, Web traffic anonymizing, and
a signature-based filtering engine. All filtering
is done on the fly, without blocking downloads in
any case. It uses only POSIX primitives and is
built with autotools, and was created with
security in mind.
