It is possible cache of dynamic pages, especially the home page?
For plan to reduce access to the database .
I can do static file cache. perfect.
Response headers

Your backend is screamming it doesn't want anyone to cache the page:
Cache-Control:no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Expires:Thu, 19 Nov 1981 08:52:00 GMT
Pragma:no-cache
It's setting all the Cache-Control headers to disallow cache, it's setting an Expires header in the past (way back), and a Pragma: no-cache. You either have to fix the backend to send headers that allow caching, or if you are sure that you won't break anything start to workaround this headers in vcl.
I would choose the first option, and work the Cookies issue later.
