The X-Content-Type-Options HTTP header has only one possible value: nosniff. It prevents Internet Explorer from MIME-sniffing an HTTP response in some other way than from using the declared content-type. This also applies to Google Chrome, when downloading extensions. Here is an example:

X-Content-Type-Options: nosniff
