If you are going to return a list of N mirrors, make N copies of that 
list, rotating one position for each.  Knock the last octet off the 
source IP and hash the remaining part with some consistent algorithm 
that will give you N values and use that to choose the copy of the list 
you send.  Everything is as distributed and robust as before, but you 
don't defeat attempts to save your bandwidth with caching proxies.
