What is cufwUrlfRequestsNumResDropped?
This Counter64, in Requests, counts incoming URL access requests dropped by the firewall purely because of resource constraints, accumulated since the last reboot. An admin can use a rising value here to recognize that the firewall's URL filtering subsystem is overloaded rather than actively denying requests on policy grounds. A spike during a period of unusually high web traffic would point to the filtering pipeline running out of capacity to keep up.
