I have installed the Varnish and configured it to my local instance. And I have created the logs before Varnish and after Varnish as below.
And the front-end response headers.
My question is when I saw in the Final Verification from Magento docs the important headers are below as per standards.
X-Magento-Cache-Control: max-age=86400, public, s-maxage=86400
Age: 0
X-Magento-Cache-Debug: MISS
But when I run the same command I got the first image response.
I’m confusing here. Is Varnish applied to my instance? as a reference to the above images.
Please suggest me.
