I can't give you the link, because i took it down when i noticed that.
It's a project for my uni and i work on it locally too. I tried it with IE, firefox and opera from my machine, and from another machine on the local network with ie getting the same results.
*upate
after trying it again an interesting thing happened. While from my machine i was able to logout, i couldn't from the other machine. I didn't do any changes in both machines
*note: this happened in both forums, the one on my machine and the one i uploaded
