All web pages served by Checkmk will now have the HTTP header Header always set X-Content-Type-Options: "nosniff" set. It prevents a client from guessing the content type based on the provided file. This is a way to opt out of MIME type sniffing, or, in other words, to say that the MIME types are deliberately configured.
