ejecuto el blog de wordpress en el servidor apache de windows....

quiero configurar X-Robots-Tag "noindex" en cada contenido rss+xml

Traté de usar esta regla.

 <FilesMatch "\.(rss|xml)$"> Header set X-Robots-Tag "noindex" </Files>

Todavía no puedo encontrar X-Robots-Tag "noindex" en la respuesta del encabezado http

¿podría ser debido a un bonito alias de enlace? ya que la URL termina con el carácter "feed", no rss o xml como este

 htttps://www.domaincom/feed https://www.domaincom/post.html/feed
