It seems like alot of people are focusing on what you can't do. As the client seems not to care, you could take the immediate approach and mimic several other online education sites, combining JavaScript to monitor the browsing habits and submitting a php script when the page is left. IE, use onload/onfocus to start a timer, onblur to pause it, and then onunload to perhaps popup or popunder a new window, populate a form with your necessary data, auto-submit and close that window. Sure, not entirely accurate, and you can still fool it if you have the know-how, but much more accurate than refreshing a frame every 2 minutes, and you have control of a timer than can be stopped when the user's not viewing the page. IIRC, there are several 'defensive driving' online sites that use this approach in the US. -SS -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
