    Console.WriteLine("Host address: {0}", request.UserHostAddress);
    Console.WriteLine("User agent: {0}", request.UserAgent);
}

Hinweise

Der Host Header enthält den angeforderten Serverhostnamen und die Portnummer, sofern angegeben, durch einen Doppelpunkt getrennt (z www.contoso.com:8080. B. ).

Sie können diese Eigenschaft verwenden, um je nach dem in der Anforderung angegebenen Hostnamen verschiedene Antworten zurückzugeben.

Eine vollständige Liste der Anforderungsheader finden Sie in der HttpRequestHeader Enumeration.
