Thank you all . I managed to solve the problem by studying a little about the functioning of the cookie in the varnish .

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.

I think Varnish by default does not cache pages with Cookies. Maybe that is your problem (it looks like you have a PHPSESSID and some other stuff)?

See the Varnish documentation: https://www.varnish-cache.org/trac/wiki/VCLExampleCacheCookies

Try configuring your webserver to not set any cookies, or configure Varnish to ignore them (note that that may not make sense, and break your website!)
