When I refresh page and check the header of homepage I got this below information where x-varnish-age=0 enter image description here Want to confirm if there is an issue with cacheable="false"? If any block on page is cacheable="false" so it causes x-varnish-age=0 for that page ? If yes if I have to make some block noncacheable, what should I do to make page varnish cacheable ?

I see that there's a Set-Cookie header in your response. That will cause Varnish to mark this incoming response as uncacheable because it changes the state.

If the next request for this resource doesn't return a response that contains the Set-Cookie header, you'll be fine and Varnish will store the object in the cache.

If every request returns a Set-Cookie header, the page will never end up in the cache.

As yourself why this cookie needs to be set and if this happens only once?
