With Centos 3.x you could easily pull things through a caching proxy by 
setting http_proxy in the environment from the command like:
http_proxy=myproxy.mydomain.com yum update.
and any number of machines at a location would only have to download a 
needed file once (assuming your proxy is configured to cache large 
files).  However, newer releases use a mirrorlist approach that makes 
each machine pick a different url, defeating the caching.  I thought I 
saw something about 5.x having a way to restore the old way without 
being tied to a single repository, but I've forgotten it now.
