Your browser’s cache is a collection of web pages, including the text, images, and most other media contained on them, that is stored on your hard drive.

Having a local copy of a web page makes for very quick loading on your next visit because your computer doesn’t have to download from the Internet all of that same information again.

If browser caching makes pages load faster, why would you ever want to clear your cache? A few reasons come to mind.

Firstly, clearing your cache forces your browser to retrieve the newest copy available from the website, something that should happen automatically but sometimes does not.

You might also want to clear the cache if you’re experiencing issues like 404 errors or 502 errors (among others), sometimes indications that your browser’s cache is corrupted.

Regardless of why you might want to do it, clearing your cache really easy to do in all the popular browsers in use today.

“How Do I Clear My Browser’s Cache?”
In most browsers, you can clear the cache from History area in the Settings or Options menu.

The steps involved in clearing the browser cache depend entirely on what web browser you’re using. Here some browser-specific tutorials:

Time Required: Deleting temporary Internet files in Internet Explorer usually takes less than a minute

  1. Open Internet Explorer 11.

  2. On the very right-hand side of the browser, click on the gear icon, also called the Tools icon, followed by Safety, and finally Delete browsing history…

    Note: If you have the Menu bar enabled, you can instead click Tools and then Delete browsing history….

  3. In the Delete Browsing History window that appears, uncheck all options except the one labeled Temporary Internet files and website files.

  4. Click the Delete button.

  5. The Delete Browsing History window will disappear and you may notice your mouse icon go busy for a few moments.

    As soon as your cursor returns to normal, or you notice the “fished deleting” message at the bottom of the screen, consider your temporary Internet files deleted.

Tip: Older Internet Explorer versions, like IE10, IE9, and IE8, have similar procedures for clearing the cache but please try to run the latest version of IE if you can.
