### DurationSeconds

The duration, in seconds. The value can range from 900 seconds (15 minutes) up to 365 days. If value is higher than this setting, then operation fails. By default, the value is set to 3600 seconds.

Cela comprend, par exemple :

* Les notifications par email envoyées après l'exécution d'une action :
    * Étant donné que se connecter à un serveur et envoyer un email a tendance à être «lent» (plusieurs secondes), vous pouvez retourner la réponse directement et envoyer la notification en arrière-plan.
* Traiter des données :

	if ((attempt >= max_wait_attempts)); then
		echo "Outputs remain inconsistent after $max_wait_attempts attempts. Exiting with error."
		exit 1
	else
		echo "Outputs are inconsistent. Waiting for $wait_interval seconds (attempt $attempt/$max_wait_attempts)."
		sleep $wait_interval
	fi

	((attempt++))
done

  - Select `Synchronization enabled` - `use settings from VCS` - `MyNewVcsRoot`(the one you just created) - `Settings format: Kotlin`, then `Apply`.
- At the popup window, click `Import Settings from VCS`. Wait a few seconds. 
  - If the error says "Context Parameter 'Branch' missing", it's ok. Click into the error and add a context parameter `Branch` with value `myTestBranch`. Go back and it automatically reloads.

* `expose_headers` - Indicate any response headers that should be made accessible to the browser. Defaults to `[]`.
* `max_age` - Sets a maximum time in seconds for browsers to cache CORS responses. Defaults to `600`.

The middleware responds to two particular types of HTTP request...

Isso inclui, por exemplo:

- Envio de notificações por email após a realização de uma ação:
  - Como conectar-se a um servidor de e-mail e enviar um e-mail tende a ser "lento" (vários segundos), você pode retornar a resposta imediatamente e enviar a notificação por e-mail em segundo plano.
- Processando dados:
