Learn Performance - Caching

This page returns a cache-control: no-store response header. This instructs the browser to not cache the response.

The timestamp above was generated on the server and shows the freshness of the server's response. This value is updated once every 60 seconds. If you refresh the page and 60 seconds have elapsed, this value will be updated with the latest server time. Throughout this demo, it will be used to demonstrate whether the server response is stale or fresh. On your website, this is likely to be data retrieved by the server from a CMS or API.

Note that The "Lorem ipsum" dummy text beneath the horizontal rule below is only used to inflate the server's response size and may be ignored.
