I would like to bring to your attention a product that does exactly what
you describe and even more.
As I understand you would like to be able to filter active content by
having the content checked for any possible risks and drop / pass it
according to a rule set.
Finjan company www.finjan.com has Surfin' Shield and Surfin' Gate.
Surfin' Gate is installed beside the firewall and works as a httpd proxy.
It checkes every applet and decides whether to pass it or not according to
an enterprise security policy. The filter can only check bytecode so only
Java applets are checked. ActiveX can be let in or not. Surfin' Gate knows
how to work with some firewalls such as CheckPoint's and Raptor's where
the firewall sends the applets to the Surfin' Gate using a special
protocol, and so the Surfin' Gate doesn't act as a proxy and becomes
Surfin' Shield is installed on the desktop computer and checkes the
activity of running Java AND ActiveX. If an applet performes an ilegal
action, Surfin' Shield stops it from running.
