Wouldn't that be only if the file is defined in the URL, right? How would we then know if the question is referencing a MIME?

If a specific file is defined, you classify on that file and therefore use match protocol http URL.

Yes, this is always an elusive subject in the understanding...when the questions can ask many different things. For example, limit the download of a specific file to a certain amount of bandwidth. Is this a file type or a MIME. So, when does a file type apply, or, a MIME?

Quetta,
This has been discused a few times on this list in the past. The bottom line
is that gif or jpeg can be either a mime type or a file extension. If the
classification includes a period, it infers a file extension is being
referenced, if a file type is referred to, it means a MIME type.
Hope this is clear.
