Yep. Keep-alive is your friend. If you use Apache or similar web server where keep alive means using a lot of RAM, you can place HAProxy or similar load balancer in front of it. HAProxy keeps the connections with browser alive, while connections between HAProxy and backend web server are closed and re-established all the time. Of course, this means that SSL is terminated on the load balancer and not the webserver.
