Block youtube, but allow youtube videos inside another website

[staboi]

Hi experts,

I was wondering if there is any trick to allow youtube videos in some website [eg. capeklah.com], but block access when the user is trying to access the actual www.youtube.com. Is there any specific methods to successfuly execute this?  I made some policies & I have https inspection enabled. Any help would be greatly appreciated.

Thank you.

I do not think this is actually possible.

You could try to use Regular Expressions in a tricky way, but mostly, websites have embedded youtube links, so the actual stream still comes from youtube and will be blocked.

You could explore a custom AppC signature to try match the referrer in the request, whilst I've not tested it I wouldn't imagine that it is still a reliable approach with modern browsers.
