If the user can VIEW the file then how can you make the difference between VIEW and DOWNLOAD ?

Answer: you can't.

To view a file, the browser should download it and store into it's local cache. You do not have any way to prevent this.

What you can do is to restrict the access to the directory (or the resources) with a htacess security asking username/password.
