How to send data to multiple users (around 500) in a synchronized way using asp? For example, i want to set up a real-time online quiz for students and it&#039s important they all received data at same time because i need to compare their answer by the response time. I&#039m looking for a kind of push technologie.<BR><BR>I tought at a kind of timing using a refresh (or response.redirect) with a time check and a if-then-end if who was able to determine if it&#039s time to load the new page or not, but it&#039s not as synchronized as i want to.<BR><BR><BR>Thanks<BR><BR>Etienne<BR>etiennemat
