That code was generated using the dancer2 -a MYAPP script, with just
"Use Dancer2" in the bin/app.pl script and Dancer :syntax in the lib.
Studying Dancer2 a bit more, now I think that every lib file should
have its own "Use Dancer2" to correctly set up an App... am I right?

I found that way for forwarding using before hook in a Dancer2 test:
https://github.com/PerlDancer/Dancer2/blob/devel/t/path_info.t
It works, but i think that it doesn't flush the session so
session changes are ineffective.
So my question now is: how can I communicate data to the forwarded path
from the one doing the forward?

Thanks for all,
Simone
