Caching is the technique of storing frequently used items in memory so that they can be accessed more quickly.
By caching the response, the request is served from the response already stored in memory.
It’s important to choose the items to cache wisely as Caching incurs overhead.
A Web form that is frequently used and does not contain data that frequently changes is good for caching.
A cached web form freezes form’s server-side content and changes to that content do not appear until the cache is refreshed.
