Your computer stores the files that it downloads from the internet and displays in your browser. It does this so that, when you visit a web site for a second time, you don't have to download everything over again. Sometimes your browser shows you the file that is in your cache instead of grabbing a newer version of it from the internet. In order to see the latest version of the file, you have to empty your cache, forcing the browser to get it from the internet again.
