I have two webservers colocated in the same place. Currently only 1 is active and it hosts a online forum, but it's biggest use by far is serving large binary files to a couple hundred thousand people and responding to automated update checks. Users reported that there have been some issues so I got the second webserver to share some of the load (I'm rsyncing between the two). How can I implement an effective (simple) load balancer for these two servers? The facility doesn't offer any sort of load balancing for me.
Round robin seems ineffective and not really a proper choice.
