Implementing caching on a website is very necessary to increase its performance. There are some steps for caching implementation in a website. At first, server-side caching can be established using Redis, Memcached or Varnish etc., which keep web pages often accessed, database queries or API responses in memory. Browser caching means setting up cache-related headers on the server response so that the browser caches static resources like images, CSS files and JavaScript files. By employing CDN (Content Delivery Network), static contents can be cached and served from servers closer to visitors thereby reducing latency. Frequently access data or objects are cached in memory to improve response times known as object caching. Cache should be invalidated when content changes while content compression such as GZIP or Brotli reduces data size for faster downloads . One should also tune caching system for best performance.
