I have an idea how to setup Apache for doing load balancer based on mod_proxy and mod_balance modules. But in my case the backend server requires ssl client certificate authentication and therefore the Apache Server cannot terminate the ssl connection.
I do no need http session cookie stickyness. The application is stateless. Can I somehow configure Apache as a transparent balancer?
Or I should use even another software - squid, iptables? The backend application is a web service running on Tomcat.
