Webfilter not fully allow the website

Hi, 

I blocked the Social Networking category on the firewall but attempted to exempt one specific site, facebook.com, by adding it to the static URL filter with the action set to Exempt. While this allowed the main site to load, certain elements such as logos and images were still blocked.

Upon reviewing the logs, I discovered that Facebook relies on additional content delivery domains (e.g., static.xx.fbcdn.net) to fully render the site. Since these dependent URLs were not included in the exemption, they were automatically blocked by the firewall. After explicitly allowing these domains, the website loaded correctly and became fully functional.

The challenge is that the firewall’s static URL filter does not automatically recognize or exempt dependent domains when the primary domain is allowed. Each supporting domain must be manually identified and added to the exemption list. Is there any way we can do this so the firewall automatically recognize it and allow ?
