One HTTP request per host, matched against an in-house signature set. Every hit carries a confidence value from 0 to 100 and the evidence it rests on: response header, asset path, cookie name, meta generator, DNS or ASN record. Results are cached for 24 hours per host, so a repeat lookup of the same domain answers from cache.Overview
