Be warned... a web server can be configured to send an arbitrary mime type for any file. You may find .jar files with a mime type of html/text. Also zipping a jar circumvents this check. Some ICAP servers have a "true content type" check that does not rely on the headers which can be forged, but actually looks at the file that was requested.
