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

[Marcus Kool]

yes, with ufdbguard you put
    youtube.com/watch?v=VIDEOID
in a urls file and create a URL table with ufdbGenTable.
ufdbGenTable adds many URLs automagically, i.e.
    youtube.com/embed/VIDEOID
    youtube.com/get_video_info?video_id=VIDEOID
    ytimg.googleusercontent.com/vi/VIDEOID
and many more.
