Reporting back that the problem has been solved. Apparently this issue
(wrong web page displays with a certain URL) arises from the
implementation of IPV6 in Fedora Core 2 (kernel 2.6 - apparently other 2.6
distributions also have IPV6 issues.) I suspect the issue on this one PC
is aggravated since it is also an Apache server. 

Apparently Mozilla and Firefox both pick up on this factor and create this
error. (A companion problem is that some web pages load very slowly due to
this issue - drudgereport.com is an example.) Opera didn't have this
problem so assume it uses (or doesn't use) IPV6 differently.

The fix is to turn off IPV6 implementation in the 2.6 kernel. This is done
by editing the /etc/modprobe.conf file and adding the lines:
  alias net-pf-10 off
  alias ipv6 off
and then rebooting the system. 

This fixed the original problem and also sped up loading of certain web
pages that were somewhat slow. (While the other FC2 boxes didn't have the
one wrong URL error that the server did, this fix did improve their
display of previously slow web pages.) 

I assume that over time the implementation of IPV6 will improve and it
won't have to be disabled to have credible performance.
