#Caching

Caching stores ready-made copies of files and pages so they do not have to be rebuilt or downloaded again. Articles tagged here explain browser caching, page caching, object caching and CDN caching. They show which cache headers to set and how long files should be kept. You will learn how to avoid serving stale content after an update. Guides cover common setups for WordPress and custom servers. A correct cache setup often cuts load times more than any other single change.
