It’s just data


Eric Lawrence: we’ve provided web-applications with the ability to opt-out of MIME-sniffing. Sending the new authoritative=true attribute on the Content-Type HTTP response header prevents Internet Explorer from MIME-sniffing a response away from the declared content-type

While I’m not a fan of content-sniffing, one of my few pet peeves with HTML5 is that it endeavors to institutionalize the practice with no provisions for content providers to opt out.  As the lesser of the available evils, I hope Microsoft’s proposal is quickly adopted by other browsers.
