There’s more to this though. It has its downfalls too. Let’s take a closer look.
Introduction to WordPress Cache
The caching process begins whenever a user visits your website for the first time. WordPress sends a query to the website’s database in its programming language. The data is brought to the core to generate an HTML page. The user can now display the page.
It’s a pretty complex process with multiple steps. It takes a few seconds to load. Do you think users will appreciate this time lag every time they open your website? No. This is where cache comes in. The WordPress caching system enhances your website’s performance. It improves your loading time and functionality.
The WordPress caching system is used in two ways.
The first is client-side caching, also called browser caching. Here, the static HTML pages are kept on the user’s device. It’s a pretty fast process. Whenever they visit your website, a copy is loaded from their device.
The second is known as server-side caching. This is used to improve efficiency. It helps websites with large databases. All it does is store the static pages on the server’s hard disk or RAM.

The situation is more common than you think. This occurs whenever you update your WordPress theme. It may occur when you change or update your plugins too. Any new content you share leads to the same problem. Let’s not talk about the time lag your users face when you migrate to a new host.
