The easy way 1. Have a hidden I frame on the page that refreshes every X seconds, and when it finds something new refreshes the main page 2. Use Ajax call on a Javascript Timer to check the server every X seconds 3. Use Flex push technology
PS: 2 & 3 will be much easier in CF8. These are the easy options, 1. Is the easiest as there is no learning curve, 2 isnt much harder.
