I’ve have reviewed all the CF docs many times, and have tried a number of tools (page redirects, bulk redirects) within CF to make this work, but can’t. So show me what I’m doing wrong:
I have a domain pointing to a website, such as mysite.com. Works fine. (A root record and CNAME www record).
I have a subdomain which I want to redirect to another external URL, such as YouTube.
In DNS records, I set a new “A” record of “yt” as a subdomain of mysite.com (yt.mysite.com). I’ve also set the IP address to proxy, 192.0.2.1, orange cloud on.
In Bulk redirect rules (using the form - and I have a ruleset in place), I set the source to “yt.myslte.com/” (so it picks up both non-SSL and SSL traffic) and the target to “https://www.youtube.com”. No other keys are set. (I’ve tried subdomain checkbox with no luck).
I get a blank screen (DNS Probe) when browsing to yt.mysite.com, cleared cache and session cookies, same problem.
Thanks for sharing the actual domain. I saw what you saw. If you tried to visit before the name existed, your DNS resolver may have cached the negative response. I often use an external public resolver to prevent negative cache from reaching my own resolvers. Lower level CLI tools like dig and curl provide better visibility into what is actually happening. Currently the lk host does not exist.
