The Website Caching Bible

Introduction
It is widely acknowledged that websites are crucial for branding, SEO, and, more importantly, driving business success. In order to make sites more efficient, one of the mechanisms available is website caching. During high traffic, caching plays a vital role in maintaining performance by reducing server load. This guide — The Website Caching Bible — will discuss everything related to caching, including solving problems and maximizing performance.
What is Website Caching?
Caching revolves around the concept of designing web content in such a way as to lessen server reliance for effective content delivery. Response time is the time taken before a command is executed, and during this time, a page is being rendered. Instead of recreating a webpage every time it is requested, a cached copy is made available instantly, thereby reducing load times.
How Does Website Caching Work?
Although caching might sound complex, it revolves around a straightforward process:
- Without Caching: When a user visits a webpage for the first time, the server creates the content dynamically, combining database queries, HTML, CSS, and JavaScript to display the page.
- With Caching: For subsequent visits, the server delivers a pre-saved cached version of the webpage, significantly reducing load times and server strain.
This process reduces the server’s burden and enhances user experience by speeding up load times.
