Following REST conventions, an OPTION call is being made before the GET call.

To quote the spec:

This method allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.

Preflight that causes confusion --> Preflight is an additional request the XHR object makes to make sure it's allowed to actually make the request
