Sorry if I'm missing something... But in your very first example:

Let’s say we’re trying to fetch some user information on our website from a server that’s located at

And it goes through fine... How come this is not a cross origin request? It's a different domain and subdomain isn't it?

You are correct. It's just an intro showing a request that works followed by one that fails. They seem similar, but are being affected by the same-origin policy. has to be returning Access-Control-Allow-Origin: since the second example denies the request coming from

I believe that's a typo. Should both be, otherwise it's a cross-origin request
