Hinweise

Der Host -Header enthält den angeforderten Server Hostnamen und die angegebene Portnummer, die durch einen Doppelpunkt getrennt sind ( www.contoso.com:8080z. b.).The Host header contains the requested server host name and port number, if specified, separated by a colon (for example, www.contoso.com:8080).

Sie können diese Eigenschaft verwenden, um je nach dem in der Anforderung angegebenen Hostnamen unterschiedliche Antworten zurückzugeben.You can use this property to return different responses depending on the host name specified in the request.
