System and method for improving efficiency of SSL/TLS connections

Abstract:

A system for optimizing network traffic is described. An appliance operates within a cluster of appliances. The appliance includes one or more network interfaces to facilitate a first secure session between a client device and the appliance, and a second secure session between the appliance and a server. One of the network interfaces is configured to receive a secure connection request to the server. A secure session exchange module acquires a message from another appliance, with the message indicating that the other appliance is acting as a primary instance for the server. The secure session exchange module determines whether a valid primary instance for the server exist, and requests from the other appliance at least one session-related parameter based on determination of existence of the valid primary instance for the server. A session to the server is used based on at least one session-related parameter acquired from the other appliance.
