www.gnustep.org is handled by 3 differents servers:
and "orginal" web site content come from cvs.net-community.com CVS server.

When you do a dns query on www.gnustep.org, 3 IP adresses are returned and your 
application choose one of them but not always the same. These DNS entries have 
a 10 minutes expiration date.

Each server update its content from the CVS server but not as the same time.

So if you go to www.gnustep.org multiple times, you can reach the same serveur 
(if DNS not expired) or another server (if DNS expired and if your application 
choose another IP). So sometime, you see an up-to-date page (when the serveur 
has already done the update), sometime the previous page (when the serveur 
hasn't already done the update).

Strange but logic :-)
