[dancer-users] Tiny problem with sessions in a Dancer2 plugin

[Gideon D'souza]

I found the source of the problem, and it still leaves me hanging.


For some hideous reason, if I redirect after making the request for the
users json data, the session is undef in the main application. However, if
I don't redirect. Then goto the homepage from the browser, it accesses my
session! :S


my $jresp  = $browser->get("https://api.github.com/user?access_token=$acc");
my $json = decode_json($jresp->decoded_content);
$dsl->session(github_user =>  $json); #also tested by just setting a string
instead of json!
$dsl->session(github_access_token => $acc);
return "done";   #This works fine!
#but if I # return $dsl->redirect("/"); #it doesn't work !


And worst of all, if I take your code and do this:

  my $controller = sub { $dsl->session(user =>  "Yippikiayeeeh");
                      return $dsl->redirect("/");};

it works! but for me it doesn't me. The session goes undef.

I tried it with a YAML backend and the default (simple session)
