Overview

Rack Middleware that sets the ‘rack.session’ environment variable with a new Hash object.

This is specifically useful for when an application, or other middleware, assumes that a rack session is set yet the developer doesn’t want to save an actual Cookie or Database session.

For example, one may want to use API tokens for authentication in a rack application protected by ‘warden`. Each request requires the API token for each call and we don’t want the authenticated user to be saved in a Cookie session.

Simply:

use Junkfood::Rack::TransientSession
use Warden::Manager do |manager|
  manager.default_strategies :web_api_access_token
  manager.failure_app = Junkfood::WebApi::UnauthenticatedHandler.new
end
use Junkfood::WebApi::AccessTokenAuthentication
