Caching is a process of storing data in a memory cache so that future requests for that data can be served faster. When you visit a website, your browser stores or “caches” certain files from that site on your computer’s hard drive. The next time you visit that site, your browser can load the page faster because it doesn’t have to download those files again.
How Caching Works
There are different levels of caching, each designed to speed up webpages. Browser caching stores static files on a user’s computer so that the browser doesn’t have to download them every time the user visits a page. Server caching stores static files on the server so the server doesn’t have to generate them every time a user visits a page. And finally, CDN caching stores static files on a content delivery network (CDN) so users can access them more quickly from anywhere in the world.
Why Is Caching Important?
Caching is important because it helps improve website performance and speed. By storing data in a temporary memory cache, subsequent requests for that data can be served faster. This is especially important for websites that receive high amounts of traffic or have complex database queries. Caching can also reduce server load and save bandwidth, which can lead to lower hosting costs.
