Blocking YouTube Videos
Warning: Any example presented here is provided "as-is" with no support or guarantee of suitability. If you have any further questions about these examples please email the squid-users mailing list.
This example covers the blocking of all YouTube.com videos. Which is actually very easy.
Caching them is now impossible, for information on that see ConfigExamples/DynamicContent/YouTube/Discussion
Squid Configuration File
Add this to squid.conf before the part where you allow people access to the Internet.
As of Feb 2014 Google are using one subdomain of youtube.com for authenticating all google services, including Docs and Gmail. If you were intending to block only YouTube access this needs to be whitelisted from the denial.
## The videos come from several domains acl youtube_domains dstdomain .youtube.com .googlevideo.com .ytimg.com ## G* services authentication domain acl gLogin dstdomain accounts.youtube.com http_access deny youtube_domains !gLogin
Other sites than YouTube also host this kind of content. See the Flash Video section of ConfigExamples/Streams/Other for general flash media patterns withut needing to block specific websites.
To block not all YT, but some clips, use focused acl rule:
# Block YT clips acl yt_clips url_regex .youtube\.com\/watch\?v=lr_m3GW5Cws http_access deny yt_clips
You also can specify clips list as file.
