Cache section overview

This is the section of the Presslabs dashboard where you can manage the cache for various zones of your site. For performance reasons you need to wait 5 minutes between cache flushes as this can induce a lot of stress on the servers if it's used under high traffic conditions. The Refresh URL section doesn't have any limitation and can be used as often as needed.

Refresh URL

Use the Refresh URL field to individually refresh the cache for a certain URL. The URL can be the front-page of your site (when you just need to click on the Refresh button), it can be an article page, a CDN resource (e.g. the direct link to a CSS or JS file) or any other URL from your site. Please note that this button doesn't delete the existing cache, but performs a cache refresh, meaning it will regenerate the corresponding resource again.

Flush caches

This section has two buttons, with separate use cases for each:

  • Flush Page Cache - this is used to remove from our caches all html files that are corresponding to your site's pages. This includes the front-page, article pages, category pages, tags and all other archives of your site. This process is useful when you are changing certain parts of the HTML of your site. This includes updates in the ad codes, activating certain plugins, modifying widgets on your site as well as a complete theme change. Flushing the page cache will not remove from cache any static resources like images or CSS/JS files.

  • Flush CDN Cache - this is the counterpart of the button above and will only flush the static resources (images, CSS & JS files, etc.). This is especially needed when you regenerate your thumbnails following a theme change or just a simple thumbnails reordering, because otherwise you'll still see the previous versions of the thumbnails.
