[dancer-users] Managing session in before hook

[David Golden]

I'm not sure what exactly is the problem, but I'm perplexed why you're
importing only ":syntax" -- that means your code isn't setting up a
dancer app properly.  And you're calling forward from a hook and I
think that might only valid from a request handler.

Here's a simple example that works:

https://gist.github.com/dagolden/5810631

If you run that and go to the localhost URL, you should see "bar" (as
set in the session).

I hope that helps you get on the right track.

David
