overrideHost only works sometimes #146

If I have a site with many images all on the same host and I try to toggle out 
that host with another, using overrideHost

For example, this script:

overrideHost    nebula.phx3.secureserver.net videosak2.video.me
navigate    http://theme21.roxyrestaurantencinatas.com/home.html

resulted in this single request getting pointed at videosak2.video.me:
http://www.webpagetest.org/result/130313_PR_ZXH/1/details/#request6

The rest of the nebula.phx3.secureserver.net requests went to their normal 
origin.

In most other tries of the above script, overrideHost didn't work for any of 
the nebula.phx3.secureserver.net requests.  I was shocked when I found this 
single request worked in this run.

overrideHost just replaces the outbound Host header with the one you requested 
and puts in an x-Host header with the original.  If you look at the request 
headers you can see that happening.

If you want it to direct traffic to a different server then you need to use 
setDns or setDnsName to re-route the DNS lookups to point to the different host 
(possibly in combination with overrideHost if you also want to change the host 
name used).

Ahah!  Works.  Thank you so much, sorry for the false alarm.
