HTTP Caching

HTTP caching is a technique used to store copies of web resources, like images and webpages, closer to the user to improve loading speed and reduce server load. When you visit a site, your browser saves some data. The next time you visit, it can quickly retrieve that data from its cache instead of downloading it again from the internet. This makes the website load faster and decreases the amount of data transferred, leading to a more efficient online experience. Cache can be controlled through rules set by website owners, ensuring users receive up-to-date content when needed.
