When the server sends files to the browser, it is the server's
responsibility to include the file's Mime-Type. Whether or not the browser
accepts this (it should) is up to the browser, but the server always returns
a Mime-Type. MSIE has been known to ignore the Mime-Type returned by the
server and to instead try to figure out the file type on its own by looking
at the file's extension and the first few bytes of the file.
When a browser sends a file to the server, it is the browser's
responsibility to include the Mime-Type of the file being sent. The server
is supposed to rely on the browser-supplied Mime-Type. Coming from a
Windows-based system, it is entirely possible that the browser is sending
over "application/msexcel" instead of "application/vnd-msexcel" as the
Mime-Type. This would be Microsoft's fault 8^).
In general, whichever party to the connection is sending the content, it is
that party's responsibility to also specify the content's Mime-Type. For
more information on HTTP take a look at the preso I gave last year:
