Looks like you need to write your own sub SOAP::Transport::HTTP::Daemon::handle

sub handle {
  my $self = shift->new;
  while (my $c = $self->accept) {
    while (my $r = $c->get_request) {
## handle cookie based authentication somewhere in here
      $self->request($r);
      $self->SUPER::handle;
      $c->send_response($self->response)
    }
    # replaced ->close, thanks to Sean Meisner <Sean.Meisner@VerizonWi
+reless.com>
    # shutdown() doesn't work on AIX. close() is used in this case. Th
+anks to Jos Clijmans <jos.clijmans@recyfin.be>
    UNIVERSAL::isa($c, 'shutdown') ? $c->shutdown(2) : $c->close(); 
    undef $c;
  }
}
