How Does Cache Work?

Whenever you visit a website, your browser will download static content, such as HTML, Javascript, CSS, and image. The data is then stored as cache files in your local storage. So when you revisit the same website, it will load faster as you already have parts of the content in your device.

In other words, your browser would create fewer requests to the server, and you don’t have to download the website content all over again. That’s why caching is an excellent way to improve site performance.

You can also set the time range for the content to be stored in the cache file. For example, if you set the expiry time of images to one year, all cached images will be automatically cleared after one year. Keep in mind that setting a longer interval might prevent you from seeing the updated version of the site.

It also applies to webmasters, especially when making changes for websites. New static content might not show up since the browser is still displaying the stored data. In this case, the cache should be cleared manually.
