The Right Order of Purging Multiple Caches ∞

This article will cover how to purge multiple types of caches in a WordPress website simultaneously. Caching is crucial for website performance optimization, as storing a static version of your site reduces the time it takes to load. However, there are times when you may need to clear these caches to see the most recent version of your site. For example, when adding content, updating visuals, and more. This guide will provide a step-by-step process to purge multiple caches, specifically the Clearfy Cache WordPress plugin, Redis Object cache, and Cloudflare CDN cache.

The First Step: Purging Clearfy Cache

The initial step to purge multiple caches in a WordPress website involves dealing with Clearfy Cache, a handy plugin widely used in WordPress sites. The role of Clearfy Cache revolves around holding static versions of your web pages, decreasing the number of PHP calls necessary for the functioning of your website. Clearing this cache primarily ensures that all recent changes you’ve implemented become instantly visible at the most immediate and accessible cache level.

If you also aggregated and minified the CSS and JavaScript files, these will be purged from Clearfy Cache.

Proceeding to Redis Cache

After you’ve dealt with Clearfy Cache, it’s time to purge Redis Cache. Redis is an open-source data structure store acting as a cache, database, and message broker. Within WordPress, Redis functions as a comprehensive page caching system or an object cache backend. By purging the Redis Cache after the Clearfy Cache, you ensure that data produced dynamically or retrieved through database queries is up-to-date.

The Final Stage: Clearing Cloudflare CDN

Now that you’ve successfully purged the application and database level caches, the final stage in our guide to purging multiple caches in a WordPress website is to clear the cache of a CDN like Cloudflare. CDNs like Cloudflare speed up the delivery of your website’s content by caching static content, including HTML pages, JavaScript files, stylesheets, and images, at various global points. Clearing this cache ensures that users across the globe are served the latest version of your website’s static content.

Since Clearfy Cache and Redis Cache regenerated the pages, their updated version can now be re-fetched by the CDN network. Now, users over the globe should fetch the updated version of your website.

Clear Browser Cache

Since we use browser cache settings in Cloudflare, you should also clear all the cached settings in your browser to see the most updated version of your website.
