Cache is a collection of web pages including the texts, images and most other media contained on them, that is stored on your hard drive or phone storage. Having a local copy of a webpage helps in quick loading of the page on your next visit because your system or device doesn’t have to download the same information again from the internet.
Cached data in the browser sounds great, so why do you ever have to clear it?
You certainly don’t have to, not as a regular part of computer or smartphone maintenance, anyways. However, a few good reasons to clear cache comes to the way.
- 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 your cache if you happen to face issues like 404 errors or 502 errors, sometimes indications that your browser’s cache is corrupted.
- Another reason to delete your browser’s cache data would be to free up space on your hard drive. Over time, the cache can grow up in space and so clearing it would add up to more productive space.
If you are making frequent changes to a web page, the caching mechanism can cause confusion. Some changed elements on the page may load and some may not because your browser is still using the older, cached version of the site rather than the updated version.
To troubleshoot this, you can try hard reloading the browser which allows to bypass the cache on your system and re-download everything for the web page thereby ensuring that you are viewing the most recent version of the web page.
In Windows, the shortcut for this is Control+F5 and on a Mac, the shortcut is Command+Shift+R.
Using Developer Tools
One of the ways to clear cache and hard reload the browsers without going through the browser menu is to use the browser’s built-in developer tools. This process is usually quicker than the browser-recommended process.
Using Chrome Developer Tools
Assuming you have the Chrome browser window opened, press Control+Shift+I on Windows and Command+Option+I on MacOS. This opens the Chrome Developer Tools. When the Developer Tools console is open, right click on the Reload button. A drop-down menu with three options is displayed:
- Normal Reload
- Hard Reload
- Empty Cache and Hard Reload
Normal Reload– Uses cached data. Press F5 to initiate normal reload.
Hard Reload– Forces browser to re-download items and reload. It is possible that used resources may come from a cached version. Press Control+F5 or Control+Shift+R to initiate hard reload.
Empty Cache and Hard Reload– Cache for the page is cleared completely, and everything will be re-downloaded.
Using Firefox Developer Tools
With Firefox browser open, press Shift+F2 to open the Developer Toolbar. This usually appears at the bottom of the browser window. Type “appcache clear”, then Enter, to clear the cache.
Using Safari Developer Tools
To enable clearing of cache and hard reloading in Safari for Mac, press Shift+Command+R button on the Safari Web Inspector. To force clear a single page’s cache, click on Shift+Reload button in the address or search bar. The advantage of this method is that it does not clear all other browser caches from Safari, it focusses on that specific page only.
