I'm still not seeing it. Sure, though it's probably getting to be not worth our respective time... I want to know if CDN B serves site X. I configure site Y as an origin for my own site behind CDN B and observe what CDN-Loop header values I receive at Y. I make a request to site X twice, once with that CDN-Loop header and once without. If they give the same response, I conclude that X does not use CDN B. If the request with CDN-Loop header doesn't get content back, I conclude that X uses CDN B. -Benjamin
