video access through web filters


I am tech director for the school district. I am working with our elementary school teachers to try and get them up and going on SafeShare using QR codes. While YouTube is open for teachers, it is blocked for students along with Google Videos and other streaming media. I have an exemption in the filter so that your site is not blocked, but the videos still report as blocked. We use a Palo Alto user based filtering solution. Any ideas on how to get this to work without opening streaming videos for everyone to suck up all our bandwidth?

Hey All,

  That seemed to do the trick for my system. The teachers are very excited about being able to use it now that it works.

Thank you very much,


Hi Aaron,

That's just awesome! Please do not hesitate to contact us again if you have any issues.

Matt, do you have any update?

I'll be working with Palo Alto on our issue. I seem to have it working on PC's but mobile devices are a no-go since it still sees it as YouTube on the application level. Hopefully I'll have some good news soon.

Hi Matt,

Alright, please let me know as soon as you have any news. Hope they figure out another way to block YouTube that doesn't impede SafeShare from working too.


Our problem is that we're blocking YouTube on the application level, so even with the URL's whitelisted the traffic still gets blocked. We might have to rethink our strategy.

Hi Matt,

The "googlevideo.com" domain is completely different from youtube.com though. Does that still cause your web filter to block it?

Hi Matt and Aaron,

First of all, Aaron, I'd like to apologise for the terrible delay. It seems that I've missed the notification about your reply.

Would you please whitelist the following domain in your web filters and see if this is enough to solve your issue?

- *.googlevideo.com/* (where the videos are actually streamed from)

- *.zencdn.net/* (necessary component for video player)

Please note that this won't enable your students to visit YouTube and watch videos unsafely, as googlevideo.com isn't the same as YouTube.com, so there's nothing to worry about. 

Looking forward to hearing from both of you!

I am in almost the exact same situation and wanted to see if there was a resolution for this?



Hey Diogo,

   We can use regular expressions such as www.*.youtube.com in our whitelists and I am not afraid to call their tech support if you have something more complicated in mind.


Hi Aaron,

The easiest way for you to handle this situation without opening streaming videos for everyone (and because SafeShare really needs them to work) would be to whitelist two domains that are used for streaming the actual SafeShare videos from YouTube servers (but not YouTube.com itself).

I have a question before though: are you familiar with regex's, and are you able to use them for whitelisting/blocking domains with your Palo Alto user based filtering solution?
