You can put your DNS settings manually in /etc/resolv.conf or use RedHat's
linuxconf tool to put them there.
If we rule out:
(A) that the simple inability to resolve is causing this
and
(B) that your ISP is making you surf through a transparent proxy
(without neccesarily letting you know about it) and one
OS specifically asks to reload the page from source, while the other is
using the proxy's cache
It seems like some weird network problem.. maybe with packetsizes..
If defining DNS correctly doesn't help, see if other application protocols
suffer from the same problem (pop3 or smtp would be a good test for this).
Also, what's your MTU on your network interface and how (as in FR, dialup,
ISDN, ADSL, etc.) are you connected to the internet?
Cheers!
