CF-RAY header isn't shown in response

[jacinta]

I’m not sure if my rails app is integrated with cloudflare successfully, because CF-RAY header isn’t shown in response from my server (Rails - Heroku). But it receives cf-ray, cf-connecting-ip from request headers.

I can append cf-ray from request headers to response headers, but it seems wrong. From my understanding, when app is integrated with cloudflare. CF-RAY header will be shown in response headers automatically

Here is screenshot of full response from my server:

There is not a single Cloudflare header and the Server header is not correct either. That request did not go via Cloudflare.

Thank for your reply. I can figure out that dns was cached in all of my browsers dns and requests didn’t go through cloudflare. I tried to install brand new browser and it works perfectly!
