That PHP output looks fine.

I will have to leave it to you to configure your load balancer.

'No more impressive warning can be given to those who would confine
  knowledge and rsearch to what is apparently useful, than the
  reflection that conic sections were studied for eighteen hundred
  years merely as an abstract science, without regard to any utility
  other than to satisfy the craving for knowledge on the part of
  mathematicians, and that then at the end of this long period of
  abstract study, they were found to be the necessary key with which
  to attain the knowledge of the most important laws of nature.'
