Cache-Control Headers

Cache-Control headers are directives used in web communication to manage how browsers and servers store web content. They dictate whether content can be cached (saved for faster access), how long it should be cached, and when it should be refreshed. For example, a header might instruct the browser to keep a webpage for one day before checking for updates. This helps improve loading times and reduces server load, ensuring users see the latest version of a webpage when necessary. Understanding these headers helps optimize web performance and user experience.
