El middleware responde a dos tipos particulares de request HTTP...

### Requests de preflight CORS { #cors-preflight-requests }

Estos son cualquier request `OPTIONS` con headers `Origin` y `Access-Control-Request-Method`.

En este caso, el middleware interceptará el request entrante y responderá con los headers CORS adecuados, y un response `200` o `400` con fines informativos.
