Hi Sir June, I would recommend using OpenBSD-4.2 and hoststated as your web load-balancer: http://www.openbsd.org/cgi-bin/man.cgi?query=hoststated&apropos=0&sektion=0&manpath=OpenBSD+4.2&arch=i386&format=html http://www.openbsd.org/cgi-bin/man.cgi?query=hoststated.conf&sektion=5&arch=i386&apropos=0&manpath=OpenBSD+4.2 Caveats: Your web application (e.g. PHP) must have a distributed session across your web servers, otherwise session will break if the user move from one webserver to another.
