What is a web cache?

Category: Computers & Internet


Web CacheA web cache is a place where website data can be stored to increase speed and delivery by temporarily storing certain parts (HTML, images, etc) of a web page. So essentially after the initial website visit, any subsequent visits will serve a cached or copied version to the visitor. This storage mechanism reduces bandwidth and server load so that any future requests can be handled with the lowest possible data transfer. A web cache is a critical for larger websites or websites that may receive heavy traffic. When someone surfs the web, most of the information that is cached is stored in the browser or browser cache. The browser will typically store a local copy of all pages that have recently been visited and reuse the information when or if you return.
