OK, thanks.

I assume you meant 'comment' not 'uncomment' , which I did and it now outputs what I wanted!

Though $c->sessionid is still blank?

Hi Craig,

Take a look at the default "index" method in Controller/Root.pm.
If you look at the debug output, you will see that "index" is called after "auto". Index sets, and therefore overwrites $c->res->body.

If you use a template system, the default "end" action
(ActionClass:RenderView) will only render the template if $c->res->body is not set. But setting the body directly, as in "index", will overwrite any previously added content.

Uncomment the line '$c->response->body( $c->welcome_message );' in 'sub index ...', and you will see whatever you write to $c->res->body in "auto".

Cheers, Lukas
