RFC2616 prohibits this behaviour. Using other mechanisms to deduce
the content-type is permitted by RFC2616 "if and only if" no MIME type
is available from the sender.

I think MSIE should (indeed, "MUST") conform to the mandatory
requirements of the interworking specification, before it can rate to
be a WWW browser.

But inside their operating system they have no mechanism for
associating MIME types with files, independently of the file naming
conventions etc. Seems they've left themselves no option than to use
different mechanisms in different contexts.
