[squid-users] Squid + Squidguard Youtube URL video filtering

[Roberto Carna]

Dear Marcus, please can you tell me the way to do what you suggest?

Suppose I want to block youtube.com but enable only one URL video
"https://www.youtube.com/embed/ff9sDLGtnK8?rel=0&showinfo=0".

How should I set te DNS entries please?

Regards,
