What is Browser Cache?
When you visit a website, your web browser saves information, such as text, images, and other static content, on your computer’s hard drive in what’s called a “browser cache.”
Doing this helps improve your user experience by speeding up page loading times. The reason is, the browser cache saves the static resources you download the first time you visit a website, so the next time you visit, those resources re-download the website data from the cache (which is right there on your computer’s hard drive) instead of retrieving it from the host servers.
In other words, the browser cache is nothing more than a place on your computer’s hard disk where your browser keeps things it downloaded once in case it’s needed again in the future.
The problem is, sometimes the cached images and files cause problems on the site you’re trying to visit. That’s why you need to know how to clear your browser cache.
Browser Cache vs Browsing History vs Cookies (Compared)
Your browser cache is not to be confused with your browsing history or cookies. Here’s a brief look at each:
- Browser Cache: browser cache is the information saved on your computer’s hard drive when you visit a site that is re-downloaded when you visit the same site again.
- Browser History: the browsing history is a log of all the websites you visit over time. Browsers normally clear browsing history at regular intervals, but you can also manually delete your browser history for privacy reasons.
- Cookies: cookies are files created by your web browser, at the request of a website, that are stored on a computer. They keep track of your site visits and activity to deliver you better user experiences in the future. Sometimes you can clear cache and cookies at the same time.
Why Do You Need to Clear Browser Cache?
There are several reasons why you should learn how to empty caches:
- Clearing your cache forces your web browser to retrieve the newest copy of your website available, updates and all
- A corrupted browser may cause 404 errors or 502 errors to display when you try to visit your website on the frontend
- There may be malware inside your browser cache that needs to be cleared
- Clearing the browser cache can free up space on your hard drive (caches have size limits, which can be configured, but they do get full)
Clearing the browser cache is a simple way to empty cache from your browser and start fresh.
And the great part is, most of the time what seems like a huge problem on your website end up being just a minor one related to your browser cache.
How to Force a Hard Refresh on a Single Web Page
Before we jump into how to clear cache in your browser, let’s first take a look at how to force a refresh of a single web page and see if that clears up the problem you’re having.
Forcing a refresh on a single web page is simple to do on all the popular web browsers. All you have to do is use some pre-determined hotkeys:
- Windows and Linux Browsers: to refresh a web page, click CTRL + F5
- Chrome: to force a hard refresh in Chrome, click CMD + SHIFT + R
- Mozilla Firefox: to refresh, click CMD + SHIFT + R
- Apple Safari: to do a hard refresh on Safari, click SHIFT + Reload toolbar button
- Internet Explorer: to refresh a single web page, click CTRL + F5
Remember, when you perform a hard refresh using any of the popular web browsers mentioned above, you are only bypassing the cache for that specific page you’re on. The rest of your site’s browser cache will stay the same.
Because of this, forcing a refresh like this will only help you if you’re having trouble with one web page on your website. If the problem is site wide, you’re better off clearing the browser cache entirely.
How to Clear Browser Cache of Popular Web Browsers
Clearing browser data is easy to do no matter which web browser you use. So, let’s take a look at how to empty the cache in several popular web browsers step by step.
