Webproxy Squid - Forbid URLs with Wildcard

[Newbie86]

Hello Fellas,

i have one Simple question. In the documentation i cant find a tutorial how to forbid URLs in the Webproxy.

What i wanna do?_:
- In my Company its allowed to Surf sometimes on Facebook and Youtube but the traffic is gettin high. My Boss dont wanna forbid that but the Videos URLs should be forbidden. So See the FB Content but dont load the Video.

So how i can forbid for example *.fbstatc.com or. *.googlevidoe.com? Also the Google Safebrowsing should be forbidden. Im really sure there is a way.

Thanks for your help fellas.
