HttpCalculatorWithKerberosOverSslClientExample

En este ejemplo se muestra un cliente HTTP que usa el proxy de servicio para comunicarse con un servicio de calculadora, con kerberos a través de la seguridad del modo mixto SSL. En esta configuración, la conexión de transporte está protegida (firmada, cifrada) por SSL, que también proporciona autenticación del servidor. La autenticación de cliente la proporciona un vale de APREQ kerberos en un encabezado de WS-Security en el mensaje.
