The MIME type doesn't always (or even usually) match the file extension.

You'd also need to set the content-type to something nasty[1]. Please
don't.

Google is your friend. Well, it's *our* friend, but you could use it too.
Take a look at http://www.w3schools.com/media/media_mimeref.asp. I
cannot vouch for the veracity of the content in that table, since
www.w3schools.com isn't always accurate, but it will give you an idea of
what you're dealing with. Note especially the links at the top of the
page, leading you to the RFC (Request For Comment) documents which are
the source of this information.
