Hi, I have a domain whose DNS is controlled by cloudflare and the Cloudflare Pages is serving a static site from Github repo.
Now I am trying to redirect a specific subdomain (https://sub.domain.com) to a specific page (https://domain.com/sub or https://domain.com/sub.html)
I first read: https://developers.cloudflare.com/fundamentals/basic-tasks/manage-subdomains/
Essentially, I created Rules → Redirect Rules. Where I specified URI Full Path and gave the target address. See https://drive.google.com/file/d/1b-kT31FYnfVZI6pyn86s0qS9coIoe3Xe/view?usp=sharing
I also added a subdomain to my DNS. I tried both A record with 192.0.2.1 (proxied) and CNAME with the main domain address (proxied). Both didnt work. https://drive.google.com/file/d/1KFzGXVj29OYkNvTknZxz8w9SfgwRn4qd/view?usp=sharing
In all cases, going to a subdomain (https://sub.domain.com) on a browser gave Error code 522
You were so very close to having it match – You just need a / at the end since path is never empty, ex https://conrad.informatism.com/
I would recommend using a more exact match though, for example your match on URI Full would break if there was any query parameters.
Instead, you could do Hostname eq conrad.informatism.com
and Path eq /
Less brittle of a match.
If you wanted it to redirect any page on conrad.informatism.com, ex even conrad.informatism.com/gihgghfoigfhgoh, then you could just remove/not add the URI Path check, and just match by hostname alone.
