How to clear cache and cookies

Each time you access a file through your web browser, the browser caches (stores) it. In this way, the files (including any images on the page) do not have to be retrieved anew from the remote web site each time you click the Back or Forward buttons. You should periodically clear the cache to allow your browser to function more efficiently. All those files stored in your cache take up space, so from time to time, you may want to clear out the files stored in your cache to free up some space on your computer. This is called clearing the cache.

Web browsers store copies of pages in the browser cache (“memory”) on your computer. By doing this, the page displays faster the next time it is viewed since the browser doesn’t have to retrieve it from the web server. Sometimes, however, an update is made on the website that you don’t see because the cached page is displayed.

Normally, to see the changes on your page, you click the Refresh or Reload button on the browser toolbar or the F5 key on your keyboard. In some cases, this simply reloads the page from the cache instead of retrieving it from the web server.

Below are some techniques to totally clear the browser’s cache so you will see the changes when your page reloads.
