만약 언더스코어를 하이픈으로 자동 변환을 비활성화해야 할 어떤 이유가 있다면, `Header`의 `convert_underscores` 매개변수를 `False`로 설정하십시오:

{* ../../docs_src/header_params/tutorial002.py hl[10] *}

/// warning | 경고

`convert_underscore`를 `False`로 설정하기 전에, 어떤 HTTP 프록시들과 서버들은 언더스코어가 포함된 헤더 사용을 허락하지 않는다는 것을 명심하십시오.

## 중복 헤더

중복 헤더들을 수신할 수 있습니다. 즉, 다중값을 갖는 동일한 헤더를 뜻합니다.
