`CORSMiddleware` отвечает на два типа HTTP-запросов...

### CORS-запросы с предварительной проверкой

Это любые `OPTIONS` запросы с заголовками `Origin` и `Access-Control-Request-Method`.

В этом случае middleware перехватит входящий запрос и отправит соответствующие CORS-заголовки в ответе, а также ответ `200` или `400` в информационных целях.
