No such method. The best thing you can do is to either:<BR><BR>1. Open the page you want user to feel trapped in as a seperate window while disabling the toolbar and menubar. They can still right click on the page or use shortcut keys to go forward and back<BR>2. Set the expiration of pages so that when they do go back the page is expired and is repulled from the server. You could use session vars or the like to either permit or dispermit them accessing the page.
