Take out this rule to pass if there's a cookie on the request
(req.http.Cookie) and do a lookup instead of pass. Then it will cache
the page. But if your page changes because of a Cookie, every user
that hits the cache will have the information about the first user.

Since you use ESI, you could pass only the dynamic pages that changes,
and keep all other on cache. That's the best way to do it.

Another approach (not recommended because of the cache size and
potential to overload it) is to create one cache per type of cookie,
dealing in the vcl_hash section. For this, you can consult the mailing
list archives and documentation and there will be plenty of
information.
