VirtualHosting doesn't work. Logs me in through previous session

When I log in with one browser session, I have to log in, but when I open another session it has automatically logged me in (as if I've picked up session 1), this does not happen if I use http://192.168.0.9:9070

It forces me to log in each time. So I know the application is working, it's just the proxy server that seems to apply the loging to each session (from http://icerap.limeo.com).

VirtualHost directives have nothing to do with authentication or logging in.
