# Caching

At its core, caching is the process of storing copies of files or data in a temporary storage location, known as a **cache**, so that they can be accessed more quickly. When a user visits your website for the first time, their browser sends a request to your server, which then processes the request and sends back the webpage. Without caching, this process is repeated for every single visitor.

By implementing caching, a copy of the requested information is stored. When the next user (or the same user on a return visit) requests the same page, the cached version can be delivered much faster, as the server doesn’t have to retrieve and assemble the data from scratch. This results in a significantly improved loading speed and a reduced workload on your server’s resources.
