I give you a little not working example.
In the main package of the Dancer2 project I have:

package project;

use Dancer2 ':syntax';
use Dancer2::Template::TemplateToolkit;

hook before => sub {
    my $context = shift;
    my $newpath = '/there';	
    //this or any other of the ones I said
    $context->app->session->{'foo'} = 'bar';

    //I tried also to turn off forwording with no effect
    $context->response( forward($newpath ));
    $context->response->halt;
};

then in the dispatcher:

get '/there' => sub { 
    print session('foo'); //nothing in it
    template 'index';
};

I checked the YAML file using Session::YAML after navigation. They're
all empty.
