Or you might have http_proxy set in the environment. Normally a proxy 
will add headers to the response - the hard part is knowing which server 
from a mirrorlist has the URL's already cached. If there is no way to 
compute a first choice based on a hash of something like the proxy 
server name from the header when you request the mirrorlist, it might be 
worth having a central server somewhere that could coordinate things.  A 
quick database hit seems like a reasonable tradeoff for a huge reduction 
in mirror server bandwidth.  Or an external server that could see the IP 
address of the proxy could pick a first choice from the mirrorlist based 
on that without storing anything.
