If you are viewing a page and the information is out of date, the most likely problem is the disk cache within your Internet Browser. Your disk cache is designed to save you time on the Internet; the default setting is once per session. This means that each time you log on to the Internet your browser will load the current page, but if you ever go back to this page in the same Internet session, your browser will load the original page regardless if this page is the most recent or not.
