Цей middleware обробляє два типи HTTP-запитів...

### Попередні CORS-запити (preflight requests)

Це будь-які `OPTIONS` - запити, що містять заголовки `Origin` та `Access-Control-Request-Method`.

У такому випадку middleware перехопить вхідний запит і відповість відповідними CORS-заголовками, повертаючи або `200`, або `400` для інформаційних цілей.
