HttpCalculatorWithUsernameOverSslClientExample

Dieses Beispiel zeigt einen HTTP-Client, der den Dienstproxy verwendet, um mit einem Rechnerdienst zu kommunizieren, wobei der Benutzername über ssl-Sicherheit im gemischten Modus verwendet wird. In diesem Setup wird die Transportverbindung durch SSL geschützt (signiert, verschlüsselt), was auch die Serverauthentifizierung ermöglicht. Die Clientauthentifizierung wird durch ein Benutzername/Kennwort-Paar in einem WS-Security-Header in der Nachricht bereitgestellt.
