I install varnish(5) just like here: https://devdocs.magento.com/guides/v2.2/config-guide/varnish/config-varnish.html

I make test from varnish cli

varnishd -d -f /etc/varnish/default.vcl

Debug: Child (26063) Started
200 0

Info: Child (26063) said Child starts

Everything looks ok.

But when I try run curl test:

curl -I -v --location-trusted 'https://mymagento.com'

I don't see any varnish headers.

How can I debug this problem? Or where can I look for some tips?

  1. Varnish header request only displays in developer mode.


First, make sure you are using Magento’s developer mode; otherwise, you won’t see the headers.

  1. Make sure the varnish cache set in the backend as a full-page cache in store -> configuration -> advanced -> full page cache
  • Yes, I know. I don't see headers in developer mode :). I see others Magento headers like X-Magento-Debug: 1 but not those from varnish. – Maciej May 4 '18 at 17:58
  • if possible, please paste the results. – Bilal Usean May 4 '18 at 18:02
  • @Maciej, do you got any solution for this? – anujeet Jun 17 '20 at 11:03

X-Magento-Debug is from varnish.. If you read the vcl file, you'll see X-Magento-Debug there.. it will change to X-Magento-Cache-Debug once you're in production mode
