Sorry I have strange behavior but i think but i think this code is not root of problem My request->header from route code throws the exception as Can't call method "header" on an undefined value at /usr/local/share/perl5/Dancer/Request.pm line 92. in /usr/local/share/perl5/Dancer/Handler.pm l. 101 But i cannot make a correct patch for it yet The github's branch is 'devel' I am finding a problem... 2011/11/23 Perlover <perlover@perlover.com>:

Hello,

I found a bug as i think in Dancer1 -> devel branch

Please take a look at Dancer::Deployment -> Running multiple apps with Plack::Builder

          my $app2 = sub {               my $env = shift;               local $ENV{DANCER_APPDIR} = '/Users/franck/tmp/app2';               # 'mount_at' is used to guarantee that the routes of the applications do               # not intersect               load_app "app2", mount_at => "/app2";               Dancer::App->set_running_app('app2');               setting appdir => '/Users/franck/tmp/app2';               Dancer::Config->load;               my $request = Dancer::Request->new( env => $env );               ^^^^^^^^^^^^^^ Here $request->{headers} will be undef because Dancer::SharedData->headers will return undef (my variable $_headers will be undef)               Dancer->dance($request);               ^^^^^^^ Inside here in Dancer::Handler in the sub handle_request will be initialized $_headers of Dancer::SharedData but $request object will be keep {headers} as undef           };

Thus in PSGI variant we will not get any headers through request->header('...')

I can try to make patch for this
