URL - Category over-ride not taking effect?

Is your URL category over-ride not taking effect?

When configuring firewall rules by domain you do not need to specify the subdomains.  Firewall rules will even cover the subdomains if you specify a Top Level Domain e.g. "uk" would cover all the subdomains such as bbc.co.uk). This is not the case when using domains to override a category though!

Category over-ride from CMA for an domain / FQDN applies just to the that domain or FQDN. Any subdomains must be specified with its own FQDN.

E.g. over-riding category for http://catonetworks.com to a category of your choice does not change the category for http://www.catonetworks.com

Hope you find this helpful. 

Thanks Nath​  based on your comment I have added following article that shows how to add a custom app to get around having to override individual domains.

Add the custom app in a rule and place it above the rule that blocks the traffic.
