Caching serves a saved copy of a page instead of rebuilding it for every visitor. It is the single biggest reason your site is fast.
The layers
Your site runs on the Chek Digital Engine, so the steps below assume the standard configuration we hand over at launch. If anything on screen differs from what you see here, that usually means a custom workflow is in place — check with your account lead before changing settings.
Why you see a stale page
Your browser has its own cache. A hard refresh bypasses it, and is almost always the answer when a change looks like it did not save.
Clearing the cache
Publishing a page clears the relevant cache automatically. There is rarely a reason to clear it by hand.
