How to Cache Dynamic Content in WordPress?

There is no doubt that caching is essential for WordPress, and it’s one of the crucial ways that can make WordPress load faster. But, it’s not that easy when it comes to caching highly dynamic WordPress sites, especially those that display personalized pages to every user.

As it’s different for each user, it can’t be served to multiple users, and thus, it becomes a bit difficult to cache.

However, using the correct techniques and technology, you can cache dynamic content. Today, in this guide, I’ll share what dynamic content is and how to cache dynamic content in WordPress. So, to learn in detail, stay with this guide.

What Is Dynamic Content?

Dynamic content is not the same for all users on web pages. It varies or changes based on several factors like visit, device, location, time, user’s profile setting, user input, etc., dynamic content will change the way users interact with it. This way, it makes websites more interactive, personalized, and engaging for each audience.What Is Dynamic Content

As you can see in the image above, the dynamic content is personalized and unique for every user; therefore, caching and delivering them is not that simple.

Maximum modern websites use server-side scripts to generate all the required HTML files to render a webpage. This way, browsers compile these data to provide unique and personalized content to each user. Since dynamic content is generated server-side thus, it is served from an origin server instead of a cache.

For a long time, it was considered uncachable, but now, with the help of new technologies, it is possible to cache dynamic content. With that in mind, let’s move to the next section.

How to Cache Dynamic Content in WordPress?

Now that you know what dynamic content is and how it works, let’s move forward to how to cache dynamic content in WordPress. So, here are the ways to do that. How to Cache Dynamic Content in WordPress

1. Caching Dynamic Content on a CDN

Since dynamic content is generated by scripts, running scripts in CDNs cache instead of a distance origin server, you can generate and deliver all the dynamic content from their edge server.

To cache dynamic content, CDNs can also use a markup language called ESI (Edge Side Includes). By inserting ESI element tags into the page HTML, you can see which elements are dynamic. This way, it helps a CDN or an origin server cache only the static parts of a dynamic web page.

Now, come to the main point, actually, the exact method of caching dynamic content through CDN differs from one platform to another. But, all of these are based on a set of technologies which are known as Dynamic Site Acceleration (DSA).

Using Cloudflare CDN:

In this process, you can use Cloudflare CDN and set up serverless JavaScript functions by using Cloudflare Workers, which runs on CDN PoPs. Also, using these custom serverless functions, you can modify your site’s HTTP requests and responses, generate new responses, and make parallel requests.

Cloudflare workers can respond to a variety of events and inputs, such as device type, time, location, third-party APIs data. Now, based on these parameters, Cloudflare generates dynamic content and serves to client’s devices. To make this process even more effective, you can combine the serverless functions with ESI tags.

Also, you can use Cloudflare Page Cache Plugin to implement edge caching on your site.

Using KeyCDN:

With Key CDN, you’ll get two different options to cache dynamic content. The first one is using KeyCDN API, which helps instantly purge the CDN cache based on user actions. This way, users can always see the latest dynamic content.

The second method is, modifying the cache-control headers to direct a client on how and when to cache responses and for how long.

2. Caching Dynamic Content Using Plugin

The simplest way to cache dynamic content is using a caching plugin like WP Rocket. This plugin can sense static and dynamic content automatically. If you have pages with huge static content and little dynamic content, this plugin can still cache those pages by serving the dynamic elements via JavaScript / AJAX.

As the JavaScript files run on the browser or client-side, the dynamic content will get updated on the cached page served to the users.

Conclusion

Dynamic content caching greatly helps achieve better SEO, improve TTFB (Time to First Byte), conversion rates, and reduce hosting costs. In fact, you’ll see an amazing effect on the performance of your site once expanding your cache to include dynamic content. This way, it ensures that your users are getting all the latest up-to-date information on your site quickly.
