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