How did you change my webpage? You might have asked a simple question that is already answered on my site or easily answered elsewhere. In such cases, I don't type out the same answer for the thousandth time, I just reload your webpage with a page that answers the question. Don't worry, I didn't have to hack your computer to accomplish this. The trick is very simple. Once the page is loaded, a javascript routine on the page makes an AJAX call to the webserver every 10 seconds asking for updates. On the server side, I or other admins are able to queue requests for your client, which will be grabbed by the next update and relayed to your browser. Your browser will then execute that command. There are several different commands. Some will make text on the page change, like when I make the text grow to point size 60 or the number of viewers updates. Others will make physical changes to the page such as reloading it with another url or opening a iframe on the page to display something.
