One is the VIP protocol (e.g. HTTPS on the front from the clients) and the other is the pool members protocol (e.g. HTTP in the back to the members), or the reverse. The LB device would do the translation between the two. SSL Offload is not supported in Grizzly release so this is for allowing future addition post Grizzly and extensibility.
