そのため、`User_Agent`などのように最初の文字を大文字にする必要はなく、通常のPythonコードと同じように`user_agent`を使用することができます。

もしなんらかの理由でアンダースコアからハイフンへの自動変換を無効にする必要がある場合は、`Header`の`convert_underscores`に`False`を設定してください:

/// warning | 注意

`convert_underscores`を`False`に設定する前に、HTTPプロキシやサーバの中にはアンダースコアを含むヘッダーの使用を許可していないものがあることに注意してください。

受信したヘッダーが重複することがあります。つまり、同じヘッダーで複数の値を持つということです。
