You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

* Отправьте из них сообщения.
* Затем закройте одну из вкладок.

Это вызовет исключение `WebSocketDisconnect`, и все остальные клиенты получат следующее сообщение:

```
Client #1596980209979 left the chat
```

/// tip | Примечание

Приложение выше - это всего лишь простой минимальный пример, демонстрирующий обработку и передачу сообщений нескольким веб-сокет соединениям.

    bootstrapClient: OkHttpClient,
    includeIPv6: Boolean,
    post: Boolean = false,
  ): DnsOverHttps {
    val url = server.url("/lookup?ct")
    return DnsOverHttps
      .Builder()
      .client(bootstrapClient)
      .includeIPv6(includeIPv6)
      .resolvePrivateAddresses(true)
      .url(url)
      .post(post)
      .build()
  }

# Dateien im Request

Mit `File` können sie vom Client hochzuladende Dateien definieren.

/// info

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

Z. B. `pip install python-multipart`.

Das, weil hochgeladene Dateien als „Formulardaten“ gesendet werden.
