 * Fix: Drop `Content-Length` header when redirected from POST to GET.
 * Fix: Correctly read cached header entries with malformed header names.
 * Fix: Do not directly support any authentication schemes other than "Basic".
 * Fix: Respect read timeouts on recycled connections.
 * Fix: Transmit multiple cookie values as a single header with delimiter.

That defines the metadata about the main response of a *path operation*.

You can also declare additional responses with their models, status codes, etc.

There's a whole chapter here in the documentation about it, you can read it at [Additional Responses in OpenAPI](additional-responses.md).

## OpenAPI Extra { #openapi-extra }

* `write(data)`: Записує `data` (`str` або `bytes`) у файл.
* `read(size)`: Читає `size` (`int`) байтів/символів з файлу.
* `seek(offset)`: Переходить до байтової позиції `offset` (`int`) у файлі.
    * Наприклад, `await myfile.seek(0)` перейде на початок файлу.
    * Це особливо корисно, якщо ви виконаєте `await myfile.read()` один раз, а потім потрібно знову прочитати вміст.
* `close()`: Закриває файл.

        Metadata recessive = read(existing);

        merge(recessive);

        write(result, metadata);

        merged = true;
    }

    @Override
    public boolean isMerged() {
        return merged;
    }

    protected abstract void merge(Metadata recessive);

    static Metadata read(Path metadataPath) throws RepositoryException {
