I escalated this to @fool and we both took another look today. Yes, you can redirect from a domain alias to a primary domain subdomain… and from what we looked at today, you seem to be doing it already? Is that not the case?
@sublet, we looked at your site too and your redirect is set up correctly. Your site is password-protected, so you’ll have to enter the password twice in order to get to the redirected site. But again, it seems like it’s working? It does seem like your site assets are not loading because, for example, https://bails.cc/style.css lives at https://simplybail.com/style.css, not https://simplybail.com/m/style.css. Here’s a thread on redirects with static assets that might be useful:
I haven’t dug into this any further than my simple suggestion here, but any time we’re playing with 301’s, the 301 response is truly meant to imply that a redirect is permanent, and your browser may be caching that information …somewhat permanently. Can you hit your domain/path a couple of times from the CLI to ensure that you’re getting the correct redirect code(s) back with the correct Location header(s)?
Ah thanks @jonsully, I probably should have checked if it was caching. It wasn’t properly redirecting in incognito mode so I assumed caching wasn’t the issue but I confirmed that it is properly set up and has the correct headers when hit.
