Check that Varnish is working

[Scrofolino]

Hi! I've successfully installed Cloudpanel and activated Varnish. How can I test if it's actually working? The web tools say it's not active.
Thank you!

To test if Varnish is working, press F12 in your browser, go to Network tab, refresh the page, and look for “X-Varnish” or “Via: varnish” in the response headers - if you see these, Varnish is active.
