Would it be more useful to have active healthchecking to backend servers?
Ie, periodically hit a url on each origin and mark them up/down based on
response.  Only send traffic to up servers.  I think mod_backhand does
something similar but much more complex (?).

I had started looking to add this to balancer, but I have no time.
