Are you always being told to “clear your browser cache”?
When you’re encountering problems with a website (for example, a 304 error), it’s critical to run this test.
But what does it mean to clear your browser cache, and how do you accomplish it for your particular browser?
How to Clear Cache
When you visit a website, your web browser keeps certain information from that site in a folder called “browser cache” on your computer’s hard drive.
Most of the time, this is a good thing because it speeds up your web surfing experience by removing the need to repeatedly download the same static resources as you navigate around a page.
A website’s logo, for example, is unlikely to change, so it makes sense to save it locally in your browser cache rather than having your browser download it every time you visit a new page. However, this cache can sometimes wreak havoc on your browsing experience. It’s at this point that you’ll need to erase your browser’s cache.
Why Do You Need to Clear Your Browser Cache?
Most of the time, you are completely unaware that browser caching is taking place. It operates completely behind the scenes and has little to no impact on your browsing experience. However, things do go wrong from time to time.
You may, for example, make a tweak to your website…
However, because your browser is still serving up the cached version of that resource, you won’t see the change.
Alternatively, the cache could have become corrupted and is now interfering with the normal operation of a website.
As a result, clearing your browser cache is a recommended first step anytime you find an issue on your own (or someone else’s) site.
It won’t always solve the problem, but it’s a vital first step to rule out before assuming there’s a more serious problem at hand.
If you don’t clear the cache after using local web development solutions like MAMP, you can get the “This Site Can’t Provide a Secure Connection” problem. It’s amazing how often what you believe is a “major” website bug is actually simply a caching issue that goes away once you empty your browser cache.
How to Force Refresh a Single Page
A “force refresh” is a technique you can use before erasing your whole browser cache.
When you refresh a website, your browser often sends up the cached version rather than downloading all of the assets again. However, by utilizing a few easy hotkeys, you may circumvent the cache and force a complete refresh:
- Windows and Linux browsers: CTRL + F5
- Apple Safari: SHIFT + Reload toolbar button
- Chrome and Firefox for Mac: CMD + SHIFT + R
This strategy, once again, simply bypasses the cache for the current page. It doesn’t affect the rest of your browser’s cache. As a result, if you’re having trouble with a single page, this choice is ideal. However, if you want to totally reset your experience (for example, across an entire website), you should erase your browser cache.
