To speed things up and conserve communications bandwidth, browsers attempt to keep local copies of pages, images, and other content you’ve visited, so that it need not be downloaded again later. Occasionally this caching scheme goes awry (e.g. the browser insists on showing out-of-date content) making it necessary to bypass the cache, thus forcing your browser to re-download a web page’s complete, up-to-date content. This is sometimes referred to as a “hard refresh”, “cache refresh”, or “uncached reload”. The rest of your cache is not affected.
To clear the cache:
- Go to the “Tools” menu (the three horizontal ellipsis on the upper right of the browser) and click on “History” (Shortcut: Ctrl+H).
- Click on “Clear browsing data…” (Shortcut: Ctrl+⇧ Shift+Del).
- Select the types of data you want to clear, include “Cached images and files” option.
Click the ellipsis in the upper right-hand corner. Navigate to “Settings”, “Clear browsing data” and then “Choose what to clear”. Tick only the box: “Cached data and files”
To completely clear the cache in Internet Explorer 9 and later versions:
- Click “Tools” (the Gear-shaped button on the top-right section of the browser), point to “Safety” and click “Delete Browsing History…” (keyboard shortcut: Ctrl+⇧ Shift+Del).
- Select “Temporary Internet Files” at the top, and click “Delete”. (If Wikipedia is in your list of favorites, you may need to turn off the “Preserve Favorites website data” at the top of the dialog box.)
- Internet Explorer will now silently delete the items you have chosen. Once finished, the notification bar appears at the bottom of the screen, stating that the selected browsing history has been deleted.
To completely clear the cache in Internet Explorer 8:
- Click the “Tools” menu then select “Delete Browsing History”.
To completely clear the cache in Internet Explorer 7:
- Click “Tools” and select “Internet Options”, choose the “General” tab and click “Delete Files” under the Temporary Internet Files section. If you want, you can also opt to delete cookies and browsing history.
To completely clear the cache in older versions of Internet Explorer:
- Click on “Tools” and then “Internet Options”, and choose the “General” tab. Then click on “Delete…” under “Browsing history”. In the “Temporary Internet files” section, click “Delete Files…”. You will then get a dialogue box asking if you want to delete just the temporary files, or all off-line content. Choose the latter and click “OK”.
