Documentation:Changing Browser Cache Settings
Background
When a page is loaded, it is cached so it doesn't need to be re-downloaded each time you access the page. If the page changes after a previous visit, you may want to change your browser cache settings to re-download it to get the updated page. These instructions will guide you through changing the cache setting on your browser to check for a newer version of a cached page every time the page is accessed.
