The present invention provides a system and method of managing traffic traversing an intermediary based on a result of end point auditing. An authentication virtual server of an intermediary may determine a result of an end point analysis scan of a client. Responsive to the determination, the traffic management virtual server can obtain the result from the authentication virtual server. Further, the traffic management virtual server may apply the result in one or more traffic management policies to manage network traffic of a connection of the client traversing the intermediary. In some embodiments, the authentication virtual server may receive one or more expressions evaluated by the client. The one or more expressions identifies one or more attributes of the client. The traffic management virtual server can also determine a type of compression or encryption for the connection based on applying the one or more traffic management policies using the result.

In a method and system for routing packets between clients, a packet is received from a first client connected to a secure sockets layer virtual private network (an SSL/VPN) network appliance. An identification is made, responsive to an inspection of the received packet, of i) a type of connection required for transmission of the received packet to a destination address identified by the received packet and ii) a second client connected via an SSL/VPN connection to the SSL/VPN network appliance and associated with the identified destination address. A request is made for establishment by the second client of a connection of the identified type within the SSL/VPN connection. The received packet is transmitted to the second client via the established connection of the identified type.
