You can balance ssl traffic at a TCP level using the client's IP to set affinity. The only real catch is if you have a large base of clients behind a single NAT, but in most cases traffic will balance out pretty well.
Sometimes though, you don't want affinity at all. If you don't care what backend server takes the request, you can balance the load more efficiently, and more easily rotate servers in and out of service.
