whichever CDN you end up using, the idea is you need to point to that subdomain to Stape IP listed in your container, you can infer general concepts from the Cloudflare example.
we can’t cover all of the specific of CDN providers out there (in terms of instructions) but there shouldn’t be any limitations for you to use KeyCDN
@Melvin pretty much, yes, Stape involvement in the matter is to properly validate that domain passes through the hits, everything else is to be done on CDN provider side.
