the client.

 *  **WebSocketListener has incompatible changes.** The `onOpen()` method is now
    called on the reader thread, so implementations must return before further
    websocket messages will be delivered. The `onFailure()` method now includes
    an HTTP response if one was returned.

## [Requests](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-request/)

Each HTTP request contains a URL, a method (like `GET` or `POST`), and a list of headers. Requests may also contain a body: a data stream of a specific content type.

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.
