| Module | Camping::Session | 
| In: | lib/camping/session.rb | 
To get sessions working for your application:
  require 'camping/session'    # 1
  module Nuts
    set :secret, "Oh yeah!"    # 2
    include Camping::Session   # 3
  end
Camping only ships with session-cookies. However, the @state variable is simply a shortcut for @env. Therefore you can also use any middleware which sets this variable:
  module Nuts
    use Rack::Session::Memcache
  end
