Most of the time, we need more resources to serve back end than the front end. To reduce loads that coming to backend we need some caching. Fortunately, there is a Cache-Control header. The back end can control how the front end should cache the resource by using this header. Cache-control is commonly used for image files or static files such as javascript. It also can be used to ajax JSON request or any other request. This article will show you how to use the Cache-Control header to reduce load to back end for your website.
