We consider using [Cloudflare for Saas] (
https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/) to allow our customers to use their own subdomains and point it to our CNAME.
We currently using Cloudfront (AWS) as our CDN. the problem we see is that the traffic is getting to Cloudfront, but the Host headers being sent are of our customers, and not our fallback.
Is there any solution to always send the “Host” header of our fallback so Cloudflare can serve the content in our Cloudfront without us updating and maintaing a list of “allowed domains” (Alternate names I guess) in Cloudfront (AWS, CDN) ?
