The idea come from the book "web application development with php4.0" by Ratschiller and Gerken. The web site is http://www.phpwizard.net/ The idea was to build an irc client. You may ask them wether it's a foolproof solution or not. Beside the fact that some browsers may have a timeout setting, I do not see why it wouldn't work. Philippe

Cool idea! I never heard about it. Do you know whether that works with all kinds of browsers (especially older versions)?
