HTTP headers are arguably the wrong place, but it might make sense to
have a <NOSCRIPTS> tag that would require the browser to turn off all
scripting for the entire HTML document, or somesuch. For instance,
application-layer proxies could add such a tag to all data crossing the
firewall, and places like Hotmail prepend such a tag to all HTML-formatted
email they receive before displaying it to the user. Of course, we would
have to trust browsers to respect such a tag, but it could potentially
give a very simple, high-assurance way to turn off dangerous features.
