server: always start a new session on connection: The session was kept when a user was connecting from service profile (but not from other profiles), this was leading to session fixation vulnerability (an attacker on the same machine could get service profile session cookie, and use it when a victim would log-in). This patch fixes it by always starting a new session on connection. fix 443
