[dancer-users] Route dispatch

Fri Dec 28 20:03:21 GMT 2012

What you're describing here is on purpose in Dancer 2, it's called "app
scoping".

Anything you do in a module (a App) is scope here. That's true for route,
config entries, vars and everything you do.

If you want to share information between multiple apps, you should consider
using sessions rather than "vars" and share the session engine between apps
like so:

set session => 'Simple'
use App1 with => { session => engine('session') };
use App2 with => { session => engine('session') };
