How to clear cache in different browsers
Any website you visit consists of thousands of media files, and sometimes it may take a lot of time for a browser application to load all the website’s content. The first time you visit a site, your browser duplicates original values of the website in order to make it load faster next time you visit it. This process is called caching.
