HttpCalculatorWithUserNameOverSslServiceExample
In questo esempio viene illustrato come usare l'host del servizio per ospitare un servizio calcolatore tramite HTTP, con nome utente tramite sicurezza in modalità mista SSL. In questa configurazione la connessione di trasporto è protetta (firmata, crittografata) da SSL che fornisce anche l'autenticazione server. L'autenticazione client viene fornita da una coppia nome utente/password in un'intestazione di WS-Security nel messaggio.
