Caching for some cookies?

Finally everything is resolved. I should have read more carefully the
documentation:

- Official varnish modules (from https://github.com/varnish/varnish-modules)
work only with varnish 4.1

- There's another repository (from
https://github.com/nigoroll/varnish-modules/) that works with the latest
version of varnish (from https://github.com/varnishcache/varnish-cache)

The original problem was because beresp.http.set-cookie contains *only the
first set-cookie header*. I believe this should be stressed in
documentation and maybe implement something like an array because it's a
bit confusing. However for anyone stuck with something similar, you'll need
the header module form varnish modules.
