I have been wanting to setup a high availability load balancer for some time and just read this HowTo. http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-heartbeat-on-debian-lenny-p2 My question is, can I use this setup in front of a server running ISPConfig3? To adopt the setup to my configuration, the ISPConfig3 server would be either web1 or web2 in the HowTo article. How would you replicate the data between the two machines?
