A normal reload often serves the page from the browser's cache, which means you can be looking at slightly stale content even after a refresh. A hard refresh fixes that.
A hard refresh clears the cached copy and fetches the page fresh from the server. Auto Refresh has a built-in "Hard Refresh option" so every automatic reload pulls the true latest version — not a cached one.

Browsers cache files — images, scripts, stylesheets, and sometimes the page itself — to load pages faster. On a normal reload, Chrome is allowed to reuse those cached copies, which means you can refresh a page and still see old data if the server told the browser the cached version was "good enough". That is exactly the situation where people say auto refresh "isn't updating".
A hard refresh tells the browser to skip the cache and fetch everything fresh from the server. In the Auto Refresh Page extension, turning on "Hard Refresh" applies that to every automatic reload of the URL, so each cycle pulls the genuine latest version of the page rather than a stored copy.
Hard Refresh is the fix for stale, cached pages, but it is not always necessary. Many sites already send fresh content on a normal reload, and for those a soft refresh is lighter and just as accurate. Reach for Hard Refresh specifically when you can see that the page is not updating even though you know the data behind it has changed.
Because it re-downloads the page's assets every cycle, Hard Refresh uses a little more bandwidth and CPU than a normal reload. On heavy pages, pair it with a slightly longer interval so each refresh has time to complete. And since the option is per URL, you can apply it only to the pages that genuinely cache too aggressively.
If your auto refresh seems to "not update", the cache is usually why. Turn on Hard Refresh and every reload fetches the genuine latest page — exactly what monitoring is supposed to do.
A hard refresh clears the browser cache and fetches the page fresh from the server, so you see the latest content instead of a cached copy.
A soft refresh reloads the page but may reuse cached files; a hard refresh clears the cache first and re-downloads everything.
Open Advance Options and tick "Hard Refresh", then save. Every auto refresh on that URL bypasses the cache.
Use it when a page caches aggressively and your normal auto refresh keeps showing old data.
Slightly, because assets are re-downloaded each cycle. On heavy pages, use a longer interval.
