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:

* `expose_headers` - Indica quaisquer cabeçalhos de resposta que devem ser disponibilizados ao navegador. O padrão é `[]`.
* `max_age` - Define um tempo máximo em segundos para os navegadores armazenarem em cache as respostas CORS. O padrão é `600`.

O middleware responde a dois tipos específicos de solicitação HTTP...
