Every time you visit a web site or access information on the internet, your computer temporarily stores, or caches, that page and its related information. On more advanced internet applications, your computer may also temporarily store secure files, user-specific data, or files that help the application run more efficiently.
Modern browsers regularly clear this cache to prevent internet web pages from conflicting with outdated data, but with some programs, or in the case of some errors, it may be necessary to clear the cache manually. Here's how you can do it on the most popular browsers.
Note: on all browsers, you can press "Ctrl" + "Shift" + "Del" to empty the browser cache.
