Wondering if Ezoic's CDN or the Caching App is effectively working on your site? This article provides step-by-step instructions to help you verify whether your site's content is being properly cached and served via Ezoic's global CDN. You'll learn how to identify cache statuses using Google Developer Tools and understand what to do if you encounter cache 'misses.' By the end of this guide, you'll have the knowledge to ensure your site leverages Ezoic's caching capabilities for optimal performance.

The easiest way to verify Ezoic's CDN is active is by checking for the x-ezoic-cdn response header in the Chrome developer console. Here's how to use this tool:

1. Press the F12 key while in a Chrome window to launch the Google developer console.
2. Click 'Network' in the bar at the top of the console.
3. Look for your domain name in the list of files (it should be right near the top of the list).
4. Click the Headers tab and look for the x-ezoic-cdn response header.
5. If the x-ezoic-cdn header says 'Hit', then the content is being served to the page from Ezoic's cache. If it says 'Miss', then it isn't. If you see 'Bypass', Ezoic's CDN is active but the URL you're currently on has been excluded from caching.
6. If you don't see the x-ezoic-cdn header at all, then chances are, caching is turned off.

If you don't see the x-ezoic-cdn header at all, verify that Ezoic's caching has been enabled via https://pubdash.ezoic.com/settings/caching.

If your cache is consistently missing, and the Ezoic Dashboard is reporting a lower than expected cache 'hit' rate, perhaps even 0%, further help is available here.
