Is your nginx/Apache site visible on the internet without any authentication?

If so, I recommend that you access your site directly, not through cloud flare with redbot.org, which is the best HTTP debugger ever, for both the nginx and Apache versions of the site and see how they compare.

Why isn’t your root page / being served from your CDN edge? Is the cloudfkare configured to not cache /?
If so, why?
