On my server, I set a policy to block some web pages like facebook at 8:30 am. I suppose that, at that time, all the blocked categories and protocols are applied. But I am surprising to see that facebook continue to be updated even if in the Real-time Monitor, it displays that Facebook is blocked. And I can send a message too.
How can I appropriately do it so there is no diplay of the web pages which categories and protocols are blocked ?
Thank you for your help.
