Subject: Re: [keycloak-dev] Fwd: Preflight for token refresh
I'm testing my UI using GWTs Super Dev Mode, which means its origin is set
to http://127.0.0.1:8888. Keycloak runs on http://127.0.0.1:8080/auth.
Yes, that requires CORS, but doesn't necessarily require a PREFLIGHT request. My guess
is that "GWTs Super Dev Mode" sets some custom headers on all requests.
