This Counter64, in Requests, counts URL access requests declined by the firewall for any of several reasons: a URL filtering server directive, a static local policy, resource constraints, or other causes, accumulated since the last reboot. Because it lumps multiple denial causes together, an admin typically needs the more specific counters, like cache-denied or resource-dropped, to pin down why requests are being blocked. A sudden rise in this counter without a corresponding rise in cufwUrlfRequestsNumResDropped would point toward policy-driven denials rather than resource exhaustion.
