Hello,
I have a very interesting question (at least in my opinion).
There is a website using PHP/Javascript/MySQL and users of the website want to get announcement of some data changes, like Yahoo Messenger shows you that you've got new emails, but without writing an application. Is it possible to make a feature for the website to make announcements? If so, is it possible to have a platform independent solution for this?
The following comes into my mind: Making a Heartbeat event in Javascript (using timeouts) for example once in every minutes and if new data appeared it can open a window. This would certainly solve the problem, however, I don't like this kind of solution, because this would kill the nerves of the users. Is there a more appropriate way to do this, like showing the message of new data for five seconds?
Thank you for your answers in advance.
