(NB this is what request.getServerName() reports; I would prefer to use
the API)

I wonder, whether and how this could be coordinated with the virtual
host configuration stuff we do in the ResourceResolver /etc/map
configuration. Maybe the ResourceResolverFactory knowing about the
mapping could implement the interface and use the /etc/map configuration
for this decision ?

I prefer the configuration property anyway because a repository property
is not congruent with how we do most of the configuration today (and
additionally opens the door for very wierd stuff like wsp selected by
client points to wspd1 for default resolution which in turn would point
to wspd2 for default resolution and so forth)
