Re: Corrections and addition on The Ultimate Cheapskate Cluster

My experiences with using pen to loadbalance HTTP over two servers with
pen and freevrrp in "cheapskate cluster" configuration are detailed here.

To loadbalance both HTTP and HTTPS however, unfortunately I had to
resort to using "Pound" instead of "Pen". Pen's HTTPS support is
currently unreliable.
