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:
