Types of Caching

Types-of-Caching
There are 3 major types of caching that can help you optimize WordPress website:

1. Site Cache:

Site cache is a type of client-side caching to store website data when the web page is requested to load. And site cache helps in delivering or displaying page content faster to the user each time as the data or files have already been saved.

This is a type of client-side caching, which means that all the stored elements are controlled by the end-user. As a website owner, the only say you have is how long content remains in the cache.

 2. Browser Cache:

Browser caching is a type of site caching built into the end-user’s web browser. Website data am elements i.e., HTML pages, CSS stylesheets, images, and other multimedia files get stored in the visitor’s browsers.

The primary difference is that the browser, rather than the end-user, controls the cache. All browsers have a cache that flushes out old files without any need for user intervention.

3. Server Cache:

Server cache constitutes different types of caching but mainly three types. This includes Content Delivery Network (CDN) caching, object caching, and opcode caching. Each store’s different content on your website’s server. The server caching can help in reducing server load.

When the page is requested, the server checks its temporary storage for the required content before processing the request in full.

Now, that you know the significance of caching and different types of cache, you might be wondering how to implement WordPress caching to your site.
