my $class = shift;
my %args = @_;
$args{proxy} ||= Plack::App::Proxy->new(
exists $args{proxy_args} ? $args{proxy_args} : ()

my $self = $class->SUPER::new(@_);
$self->{proxy} = $args{proxy}->to_app;
return $self;
}
sub _proxy { shift->{proxy} }
=method app_from_request
Takes a L<Plack::Request> object, and returns an app which will retrieve the
HTTP resource.
