What is Website Cache

Share on:

If you are into blogging or more precisely, WordPress then chances are that you might have heard about caching. What is caching? Why do we need it? How to implement it in WordPress? We will take a look at all of these in this post.

What is Caching

In simple words, a website cache stores static data in a server for simultaneous visitors. How does this work? Well, taking the example of WordPress, we have the following data flow:
Visitor -> Server -> PHP -> Database (This is without caching)
Visitor -> Server (With caching)
As you can see above, caching eliminates 2 steps and hence reduces the load on the server.

In addition to server level cache, we also have client level cache. That works in a similar way but the only difference is that it doesn’t request the resources that it has already cached.

Caching in WordPress

WordPress has many plugins to enable caching. In addition to that, we can also use server-level caching and database caching.

Here are some of the best caching plugins that is available for WordPress:
