hi, we would like to use Cloudflare WAF, but we are not sure if it’s possible to setup Cloudflare WAF as a layer between Heroku backend and Fastly?
So a request comes to Fastly first, then to Cloudflare WAF and then to Heroku app.
Is there a reason why you want to use both Cloudflare and Fastly? Both are CDN providers.
What DNS settings we should have for our domain?
You would need to get these from Fastly.
I’m not sure if it would be possible as you would need to proxy the records that they request, which may cause their system to not see the records that you need to point to their service.
