Si por alguna razón necesitas desactivar la conversión automática de guiones bajos a guiones, establece el parámetro `convert_underscores` de `Header` a `False`:

{* ../../docs_src/header_params/tutorial002_an_py310.py hl[10] *}

/// warning | Advertencia

Antes de establecer `convert_underscores` a `False`, ten en cuenta que algunos proxies y servidores HTTP no permiten el uso de headers con guiones bajos.
