IE8: opt-out mime sniffing
by nxt on Jul.22, 2008, under Other
According to a recent blog entry on msdn Microsoft has finally decided to fix a very annoying 'feature' of internet explorer. Mime-sniffing.
It always irritated me that when I specified a content-type for a web page, Internet Explorer would just look at the content and say: "your wrong" and renders the page the way it thinks you intended.
If I give a html page text/plain as content-type I intend to let it show the source, not render it as html because if I wanted that I would have given it text/html as content-type.
At least in IE8 they allow us to disable the mime sniffing by appending ";authoritative=true" to the content-type header. This way it won't hurt other browsers and we are still able to provide the mime type ourselves.
