 HTTP doesn't define a way to do this, much like the Pragma header
suggestion is a pretty bad abuse of HTTP ... suddenly the origin server
going down means you can't get the data from the proxy.

 Please don't assume half of a solution, that never works well. What you
_actually want_ is:

 "On my group my machines X, try not to download data more than once."

...at the ISP level this is solved by getting your mirror into mirror
manager directly.
 At the personal level this is likely better solved by having something
like "Have a zero-conf like service to share pacakges across the local
network". There has even been some work to do this.

 In neither case is "work around HTTPs design in yum" a good solution,
IMNSHO.
