Neste exemplo, as mensagens serão gravadas no arquivo `log.txt` _após_ o envio da resposta.

Se houver uma consulta na solicitação, ela será gravada no log em uma tarefa em segundo plano.

E então outra tarefa em segundo plano gerada na _função de operação de caminho_ escreverá uma mensagem usando o parâmetro de caminho `email`.
