I would highly recommend keepalived, which is well-written software for managing ipvs, a load balancer in the Linux kernel. Very, very fast, flexible, and extremely reliable. EDIT: ipvs/keepalived only operate at layer 3, which is one reason why they are so fast. if you need layer 7 stuff, this won't do it.
