Caching isn’t all that difficult.


Servers receive a request from the user’s browser whenever they want to access a webpage on your site. The server then processes the request (which can include running database queries) and sends the finished product to the user’s browser.


The finished product is your website, complete with all the documents and elements that give it the appearance that it has. For example, you might have images, a blog, a menu, and a header.


However, particularly for large or clunky websites, it can take some time for users to receive the entire webpage because the server must handle all those requests.


This is where WordPress caching plugins come in.


Depending on the configuration, the caching plugin gives instructions to the server telling it to store some files in RAM or on disk. Therefore, the same content it has previously served can be remembered and duplicated.


The result? Speedier loading, and happier visitors!
