Apache Reference: mod_mime, ForceType
Force a Default MIME Content Type
Syntax: ForceType A
Example: ForceType application/octet-stream
Since: Apache 1.1
When placed into an .htaccess file or a <Directory> or
<Location> section, this directive forces all matching files
to be served as the MIME content type given by mime-type.
Note that it overrides any file name extensions that might
determine the media type.
