This may apply to www.yahoo.com.
It also give the error "document not found" when you try to access it!

pg: sounds serious. for your linux check, can you also use dig or nslookup to
see if that domain is a CNAME record?

does anyone know if our app is responsible for walking through the CNAME pointer
to an A rec, or if we depend on some OS level stuff to do that?

Sorry www.Yahoo.com, may have been a false alarm, it now working again

http://sourceforge.net/projects/perl-pdf/ still has the same problem with
mozilla, but konqueror has no problems, staight through each time.

With the new build the problem has gone away, it now works ok again
for  http://sourceforge.net/projects/perl-pdf/ and 
http://www.sourceforge.net and for http://www.yahoo.com

But I do notice that I still have to do a double enter to get 
http://sourceforge.net/ or http://www.sourceforge.net to come up,
but I think that but is being investigated at (bug 81468)

Ok, then let's close this bug as WORKSFORME, and let the other bug report track
the remaining problem.
