The HTML isn't generated once and held statically -- it is generated dynamically on every request. So, whenever a page for a product or products is requested, pull the relevant records from the db, check whether each product has an active promo (i.e., whether promo_end is later than request.now), and generate the output accordingly. If you want an existing page to update its own contents (without a server refresh), you'd have to do that with Javascript, but it sounds like you're already planning to do that. > - In reference to the previous question, if the server needs to keep track > of the time left of a promotion, what happens if an email is to be sent out > 24 hours before the promotion ends?
