Could something in my page http header be breaking varnish?

I've recently installed Varnish on our staging site with Magento Turpentine. I'm getting 0 hitrate in varnishstat.

Could this be something to do with my page headers? I have number of cookies in my request & response headers. For instance I have store, currency & cookielaw cookies, but when I disabled the Magento modules generating these so that only the typical Magento frontend cookie was set but this did not make any difference.

"Varnish will, in the default configuration, not cache a object coming from the backend with a Set-Cookie header present. Also, if the client sends a Cookie header, Varnish will bypass the cache and go directly to the backend."

See: https://www.varnish-cache.org/docs/3.0/tutorial/cookies.html
