Start by reproducing the reported WhatWaf 2.0.3 invocation against the supplied URL and review the firewall fingerprinting behavior for this response. The report does not identify the expected firewall or name a file or test, so first determine the intended detection and where its fingerprint belongs; done means the response is recognized reliably without breaking existing detections.
