How To Clear WordPress Cache?

Approx. read time : 3 min

In case you have made any changes to your WordPress website and if you can’t see them on your website, then the reason behind this might be outdated WordPress cache files. This article will give you more information about clearing cache with the use of WordPress plugins.

How Does WordPress Cache Work?

Whenever you access a website, your web browser downloads the static content like JavaScript, HTML, CSS and images. This data is then stored as cached files in your local storage. Therefore, when you visit the same website again, it loads faster as some parts of the content of that website are cached.

In simple words, your browser caches the content in order to generate fewer requests to the server. As a result of this, there is no need to download the entire website content all over again. This is why caching is a great way to improve website speed and performance.

You can determine the time duration for the content to be stored in the cache file. For instance, if you determine the expiry time of images to 1 year, all the cached images will be stored only for a year and they will be cleared after that. However, it is important to note that if you set a longer time interval, you won’t be able to see the latest updated version of your website.

This is also applicable to the webmasters when they make changes to the website. New static content added to the website might not be displayed as the browser is still displaying the cached and stored data. Therefore, it is important to clear the cache manually.
