Auto_page setting with fallback routes

[murwiz]

This may well be a naive question, but here goes:

In Dancer::Plugin::Interchange6::Routes there is a fallback route intended to fire on various vanilla requests. At the end of the route, assuming it's found nothing else, it does this:

status 'not_found';
forward '404';

I was trying to make an Interchange6 application work with the auto_page directive, so I really want the fallback to not generate a 404 at this point, but instead hand off to the auto_page code. So I prepended this:

return if setting 'auto_page';

However, this just generates an empty page. Upon further digging, I figured out why:

Dancer::Renderer:
sub render_action {
my $class = shift;
my $resp = $class->get_action_response();
return (defined $resp)
? response_with_headers()
: undef;
}

In my scenario, what is being returned here is not Perly false, but --

bless( {'content' => '','encoded' => 0,'forward' => '','halted' => 0,'headers' => bless( {'content-type' => 'text/html'}, 'HTTP::Headers' ),'pass' => 0,'status' => 200}, 'Dancer::Response' )

So I have naively changed the render_action code locally to:

...
return (defined $resp and (length $resp->{content} or $resp->{status} != 200))

which seems to work. Is there a reason why render_action "succeeds" in this case (where the returned content is empty)?
