What is Caching?

Before diving into litespeed and its functionality, let’s first understand what a cache is. A cache is a hardware or software component that stores data, allowing future requests for that data to be served faster. The data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. Caching is one of the pillars of web performance optimization, the set of techniques to make your website load faster. No website can call itself optimized without a caching system in place.

When a user requests the same page, the server can quickly serve the cached version, rather than having to generate the page from scratch each time. This can greatly reduce the amount of time it takes for a page to load.

So caching gives your site the ability to respond more quickly, giving it an overall SEO boost. And perhaps most importantly, making for a better visitor experience.

LiteSpeed Cache

LiteSpeed Cache is a WordPress plugin that makes your website load faster. It works by storing commonly used data in a special storage area called a cache. When visitors come to your site, the server can quickly show them this cached data instead of processing everything from scratch. This reduces the load on your server and makes your site faster for everyone. By using LiteSpeed Cache, your visitors will have a smoother, more enjoyable experience on your website.
