Swf file restriction

Hi Noob here?! :slight_smile:

Does anyone know how to put a restriction when the url is:

www.test.com/test/test.swf

What i want to happen is that it shouldn’t be accessed and not display the swf file.
It should say ‘You are not authorized to view or access this file!’

Please help on this ASAP! Hope someone out there has the answer to this.
