Comentarios

El Host encabezado contiene el nombre de host del servidor solicitado y el número de puerto, si se especifica, separados por dos puntos (por ejemplo, www.contoso.com:8080).

Puede usar esta propiedad para devolver respuestas diferentes en función del nombre de host especificado en la solicitud.
