Yes, but this session cookie is expired at the end of the session,
making it badly suited for my needs, where state needs to be kept
*between* sessions, ie. I need "ordinary" cookies, where the expire
attribute can be set.

Why is this not encouraged? And if it isn't encouraged to mess with
specific headers, then why not make available a nice api for generic
cookie management?  :o)
