I understand, thank you for the explanations. I have installed the vmod you suggested and it works now.
I have also needed to compile varnish from sources. ( for feature help... )

The problem is simply with browsers interpreting set-cookie headers
While appending '; foo=bar' _should_ work, it _will not_ work in all
All the major browsers that I've tested have worked with sending
multiple set-cookie headers. That's not to say it's right, but it
is to say it works _for me_.
You need to for obvious reasons test this for yourself to confirm, but
my solution has always been to add additional set-cookie headers
(which you can accompish easily with that vmod).
