`Header` tem algumas funcionalidades a mais em relação a `Path`, `Query` e `Cookie`.

A maioria dos cabeçalhos padrão são separados pelo caractere "hífen", também conhecido como "sinal de menos" (`-`).

Mas uma variável como `user-agent` é inválida em Python.

Portanto, por padrão, `Header` converterá os caracteres de nomes de parâmetros de sublinhado (`_`) para hífen (`-`) para extrair e documentar os cabeçalhos.
