Ok, thanks all for your replies. Another problem is the following: - I logon to http://localhost/somewhere using X's credentials. Logon succeeds and I get redirected to http://localhost/somewhere/index.html - I logon to http://localhost/somewhere using Y's credentials. I get the login page again. I click refresh and now I get redirected to http://localhost/somewhere/index.html
In internet explorer, again, no problems.
