I got a solution for Firefox and IE but I didn\'t find any solution for Google Chrome.
Is there a way to do it in Google Chrome?
I have put together the following article which explains how I have managed to achieve this in Chrome. I hope this helps. https://www.hattonwebsolutions.co.uk/articles/how_to_logout_of_http_sessions
In short - you create a sub folder (as per Gyula's answer) but then send an ajax request to the page (which fails) and then trigger a timeout redirect to the logged out page. This avoids having a secondary popup in the logout folder requesting another username (which would confuse users). My article uses Jquery but it should be possible to avoid this.
