Remarques

L' Host en-tête contient le nom d’hôte et le numéro de port du serveur demandés, s’ils sont spécifiés, séparés par un signe deux-points (par exemple, www.contoso.com:8080).The Host header contains the requested server host name and port number, if specified, separated by a colon (for example, www.contoso.com:8080).

Vous pouvez utiliser cette propriété pour retourner des réponses différentes selon le nom d’hôte spécifié dans la demande.You can use this property to return different responses depending on the host name specified in the request.
