Caching
In short and in plain language
Caching means that content people ask for a lot is stored for a while.
The next time it is asked for, it comes faster.
This saves work on the server. The page can load faster.
If caching is set up wrong, visitors may see old content.
Definition
Caching means that frequently requested content is stored temporarily and delivered faster on the next request. This saves computing work on the server and can shorten the loading time of a page. Incorrectly configured caching can cause visitors to see outdated content.
