Se um cliente tentar enviar alguns **cabeçalhos extra**, eles irão receber uma resposta de **erro**.

Por exemplo, se o cliente tentar enviar um cabeçalho `tool` com o valor `plumbus`, ele irá receber uma resposta de **erro** informando que o parâmetro do cabeçalho `tool` não é permitido:

```json

        .header("Cache-Control", "max-age=60")
