Description of problem:
Some websites simply don't load under FC6 in whatever browser you try.
The first kernels of FC 5 (five) were oke suddendly this issue was introduced
and is still in the newest kernel (FC6). I know this because a collegue of mine
still uses that old FC5 kernel and can visit this problem site with no problems.
All other co-workers of mine (incl. me) can't visit the website.

How reproducible:


Steps to Reproduce:
1. startup browser firefox/konquer/lynx
2. goto www.onlinenic.com
3. grab a cup of coffee (or two)
  
Actual results:
VERY VERY slow site loading IF it loads after all. 

Expected results:
Get website on screen

Additional info:
I assume it's something in kernel but could be wrong, I only saw that as major
difference. I know there are a couple sites which have the same problem just
can't remember them atm.
