What happens if we send an authenticated HEAD request to https://github.com/login/oauth/authorize? We’ve concluded that the router will treat it like a GET request, so it will get sent to the controller. But once it’s there, the controller will realize that it’s not a GET request, and so the request will be handled by the controller as if it was an authenticated POST request. As a result, GitHub will find the OAuth app specified in the request, and grant it access to the authenticated user’s data.

Help me, framework!
