rack-wwwhisper
Rack middleware that communicated with the wwwhisper service to authenticate and authorize visitors.
The middleware is intended to be used with the wwwhisper Heroku add-on. For more details, see the documentation on Heroku.
NOTE: the rack-wwwhisper middleware is still supported, but the recommended and easier way to use the wwwhisper add-on on Heroku is the wwwhisper Heroku buildpack. The buildpack works with any language and framework and unlike the rack-wwwhisper middleware does not require any changes to the application code.
