Cache
In one sentenceA saved copy of something so it loads faster next time. Also the reason you sometimes see an old version of a page.
What it means
Browsers, servers and CDNs all cache files like images, styles and pages. It makes sites fast, but after you update a site, some visitors may see the old version until the cache refreshes.
How to use it
- Just updated your site and do not see the change? Hard refresh (Ctrl+Shift+R on Windows, Cmd+Shift+R on Mac) or open it in a private window.
- If you use a CDN like Cloudflare, purge its cache after big changes.
