James,
I've set the proxy in the Network Settings applet in systemsettings.
I've tried "use system proxy config" and the manual settings, setting
either to the network's squid server.  Either way I don't seem to see
$HTTP_PROXY/$http_proxy in my environment.

I've tried using Firefox in a similar fashion, either to see the system
proxy, or via manual connection.

I don't have anything set in yum.conf for a proxy.

Thanks!
