Not really,  the http request also includes the clients version of the host
it is requesting from.  This is how virtual servers work (where one http
process serves different data based on the hostname the client is
requesting).  $c->req->header( 'Host' ) provides the information needed
from the context object, but is unavailable to MyApp.pm.  cookie_domain
setting in Catalyst::Plugin::Session::State::Cookie needs to be set to
reflect the requested hostname in this case else the browser will not set
the cookie nor include it on round trips to the application if the
requested host/domain is different from the host that Catalyst believes it
is running as.  I believe a workaround for this issue is to leave the
cookie_domain setting unset which I believe will produce a cookie that is
not stating its domain and the client browser will treat as locked to the
requested host's name for the domain.



So if you want the cookie to be set on the client without worrying about
the hostname requested don't set the domain_name or set the domain_name to
the common domain for all hosts.
