Sorry, I was probably I bit tired when I wrote this. You are already
forcing a lookup so your VCL will store the reponse generated with the
request with a cookie (which is generelly a bad idea). What you need to do
is use varnishlog to look at failing request. If you can't figure it out
you can post it here and we'll probably spot the error right away.
