YahooCacheSystem is a search engine crawler. Blocking it may affect your visibility in its associated search engine. Most publishers choose to allow verified search engine crawlers.

Centinel automatically detects YahooCacheSystem using behavioral fingerprinting. When detected, you can allow it, block it, challenge it with an interstitial page, or set a per-request licensing fee — all enforced in real-time with under 2ms latency.
