We have a list of YouTube-links we'd like to allow on certain computers and has put them in a webfilter-policy as allowed while at the same time block any possibility to view others YT-videos besides the links we choose. The problem is that by putting a YT-video-link as allowed in your policy results in the entire www.youtube.com domain is treated as such. 

To clearify:

We want to block the entire internet besides this YT-link for example https://www.youtube.com/watch?v=JxS5E-kZc2s.

We put the link into a webfilter policy and apply it to a computer. The computer now blocks internet, but allows the entire Youtube.com-domain when it's only the YT-link that is supposed to be allowed. Any way to configure BSP for it to work?
