  • When adding new posts or pages.
  • Making adjustments or adding to previously created posts or pages.
  • When making changes to the design. 
  • To add new products to your online store.

Many different types of caching solutions are available. WordPress caching plugins like WP Rocket and WP Super Cache are some of the most popular ones.

WordPress Cache Vs. Browser Cache

The WordPress server cache and browser cache WordPress perform similar tasks, saving data to load web pages quicker. But, both of them do this in their distinct ways.

WordPress Server Cache

Every time a user visits your site, the website connects with the database and outputs the required files. To repeat this process again and again needs time and puts much pressure on your servers.

The solution is for your website to create a static version or snapshot of the web files and present the same file repeatedly to all the visitors, decreasing the need for database load. 

These static files are the WordPress server cache. Usually, your hosting provider manages these static files.

But, WordPress server caches are important because you can also access, manage or clear WordPress cache files using some WordPress plugins.

Browser Cache

The browser cache saves data from websites that you visit to load them faster during your next visit. Browsers use your computer hard drive as the storage for these cache files.

Different browsers have different configurations and settings for managing the cache files. But in every browser, they are used for the same purpose, i.e., for loading websites faster. 

But, the performance of cache files of the same website can vary in different browsers.

To sum it up, the WordPress server cache is maintained by your website to speed up page loads. In addition, WordPress’s cache is beneficial because you can use WP plugins to manage the cache files, adjust caching options, and clear WordPress cache files if needed, right from the dashboard.

On the other hand, the WP cache is saved on your web host’s servers for the browser cache. This ensures that visitors always have access to faster-cached files and content, no matter how they access your site.

How does Caching work in WordPress? 

When a user visits your site, this is what happens. 

  1. Your server receives a request to display the page.
  2. Your server pulls the necessary data required.
  3. Your server then sends this data as an HTML file (text file format) to the user’s browser. The user’s browser then processes the HTML file, converts it, and displays it as a web page.

Now, every time the user visits your site, your server will repeat the entire process. But, there are two drawbacks to this.

A) Takes more time.

B) Uses more server resources.

This can be avoided with the use of caches. 

A cache can store this HTML data in the browser, eliminating steps 1, 2 and 3, the next time the user visits your website. A copy of the necessary data is already stored in the caching system. It will simply process and display the stored cache files.

WordPress caching can be used and implemented in the following two forms: 

Client-side caching

Also known as browser caching, client-side caching stores the static HTML pages on the user’s local computer. Now, whenever a user visits your site, a copy is loaded from the user’s computer, which reduces the loading time, making this approach much faster.

Server-side caching

Server-side caching works differently as it is used when you have a massive website with multiple databases. 

The static pages are stored on the website server’s hard disk or RAM in server-side caching to increase efficiency. Server-side caching is not faster than browser caching, but it is still quicker than no caching.
