So, you should Clear/Purge/ Flush the Cache every time you update any Theme and/or Plugin.

You may search the website using clear cache from website and find tons of articles. But, here we have tried to describe about caching and clearing the cache for WordPress Sites.

 

What is Cache?

If this is your first time, the concept of caching might scare the living daylights out of you. So,ladies and gentlemen, what constitutes cache?

In computing, caching is storing data in temporary memory (as opposed to the main memory), so you can retrieve it in a faster manner the second time you need it.

You can also think of “cache” as the saved data, even though browsers prefer to call this “Cached Data/Files”, but that is besides the point.

As far as WordPress websites go, caching involves saving a site’s static files on your browser or on the server side. Caching in this case usually involves saving files that change rarely if at all.

You know, things like your images, CSS, JavaScript files and so on. But why cache your WordPress site? What’s the use in the first place? This question ushers us to our second section.

 

How Does Cache Work?

Cache works like magic. No really, jokes aside. In one line, cache makes your WordPress faster. How? You ask.

To comprehend how WordPress cache works, it’s paramount that you understood the basic inner workings of how WordPress builds the pages and posts your see in your browser.

Whenever you load a post or page, your browser gathers different files from your server to build the said page/post. Yes, the page/post you see is, for lack of a better word, “computed” from various files.

Gathering these resources, oftentimes from different servers, takes time. You see, the browser sends HTTP requests to the server, where they are processed before the server responds with the requested resources (files, queries, logic etc).

Now, cache is the in-between mechanism that eliminates this round trip. Instead of loading the same resources from the server all over again, your browser loads the cached copy of that site.

The direct benefit is reduced internet traffic congestion and server load, which results in faster page load speeds for your website.

This is purely because, according to the guys over at Computer Hope, accessing data from cache can be thousands of times faster than accessing the same data from the origin server (read hard disk). See, we said this caching business is easy stuff.

We have also seen websites using CloudFlare Always Online™ cache to create an illusion of being online, while the entire website is offline. In one case, the entire static content was there, but we couldn’t access videos and elements such as forms, search and so on.

However, if caching means good things for your page speeds and user experience, why would you want to clean cache in WordPress? You get the honest answer in the next section.

 

1. Clearing Hosting Controlled Cache:

Some Hosting Services have their own Caching System to reduce their server load. Some of them have aggressive Caching System which is not suitable for WordPress Environment. Some hosting uses Server Side Caching which can not be controlled from the WordPress Dashboard by any Plugin. We don’t recommend such those hosting.
