How do I clear my web browser cache?

User Notice: This guide is provided for reference only.

In order to speed up web browsing, web browsers are designed to download web pages and store them locally on your computer's hard drive in an area called "cache". The cache contains a kind of travel record of the items you have seen, heard, or downloaded from the Web, including images, sounds, Web pages, even cookies. Typically these items are stored in the Temporary Internet Files folder.

When you visit the same page for a second time, the browser speeds up display time by loading the page locally from cache instead of downloading everything again. This sometimes results in less than current versions of web pages being displayed.

You should periodically clear the cache to allow your browser to function more efficiently. If you believe that you have a less than current version of a page, please see the following steps listed below to clear the cache in your browser.
