and that is why i posted the used config snippet because
i am trying this the first time, the documentation is
poor (cipher params) and there are several bugreports
stating this behavior without SNI but they should be
fixed in the recent version

on the other hand the docs do not state how to configure ATS
for SNI nor how do you configure *different* domains with
different certificates and different IP's aka ip-based vhost

what i try to figure out is what config would be needed
if we decide sooner or later ATS in front of SSL websites
and if it is possible giving the ATS machine the ip-addresses
of the sites in question and let it connect unecncrypted to
the origin server which would stay with a single IP from this

BTW: the certifictae has the same permissions as any other ATS config
