I agree, that is the language of the spec. At least the snippet you include doesn't specify what browsers should do in this case. Do you have a bug to report here? In other words, is this causing problems at a real world site? > We should use sniffing here since the Content-Type is invalid. Some platforms sniff all network traffic (except for very specific scenarios) since the network is an untrusted place. Are you trying to fix only one specific platform here? 773597 5 mawu 2012-11-21 23:00:19 -0800 (In reply to comment #4) > (In reply to comment #0) > > the test site khanapp.com > > Content-Type: web; charset=utf-8 > > > > Both Chrome and Firefox handle this. > > Great... so if Chrome handles it at least one WebKit port does.

It looks only Qt/BlackBerry uses MIMESniffing.cpp, so with this patch, qt/blackberry will work the same way as firefox/chrome/safari. Besides, Chrome porting also uses similar solution in its mime_sniffer.cc to check if mimetype contains slash '/' and commented it's following firefox. 773599 6 mawu 2012-11-21 23:04:00 -0800 (In reply to comment #2) > (From update of attachment 175166 [details]) > What's the problem here? > 1) Just checking '/' isn't enough to identify all malformed MIME type strigns. > 2) What is different between malformed MIME strings and unknown MIME strings? And why should we treat them differently? "malform" would be too general, I will narrow down the subject. Come up with new patch... 773608 7 175596 mawu 2012-11-21 23:15:35 -0800 Created attachment 175596 Patch 774022 8 beidson 2012-11-22 10:10:03 -0800 (In reply to comment #5) > (In reply to comment #4) > It looks only Qt/BlackBerry uses MIMESniffing.cpp, so with this patch, qt/blackberry will work the same way as firefox/chrome/safari. Besides, Chrome porting also uses similar solution in its mime_sniffer.cc to check if mimetype contains slash '/' and commented it's following firefox. Apparently Chrome designed to match Firefox here. Saying it'll also act like Safari seems like a leap. Achieving the same end result as Safari does not mean the more thorough content-sniffing that's built in to Safari's networking library does it the same way. I'm still not convinced this patch is the right thing to do, but I won't r- it. 778081 9 175596 webkit.review.bot 2012-11-28 11:02:03 -0800 Comment on attachment 175596 Patch Rejecting attachment 175596 from commit-queue.
