Is it hard to make a url refresher that refreshs a page every 5 seconds, and warns you with a sound if there is any change from the last time the url was refreshed? What would be the best language to do something like that?
Any language that is there in the Web Development section of the forum.
Thats very easy, you can use META-REFRESH and you can pass the timestamp to check whether there was any change or not. If so, it'll pop-up a window.
