Snap.Snaplet.Auth.Backends.Redis

This module allows you to use the auth snaplet with your user database stored in a Redis instance.

In your initializer you'll need something like:

 a <- nestSnaplet "auth" auth $
          initRedisAuthManager defAuthSettings sess defaultConnectInfo

Redis Key Space

The following keys are used to store the user information in Redis. Be sure to avoid key collisions within your applications.

• next.userId - Int representing the next spare userId.
• user:[username] (eg. user:bob) - Hash of the user fields for user bob.
• userid:[userId] (eg. userid:2 - bob) - Stores username for userId based lookup.
• useremail:[email] (eg. useremail:[e-mail] - bob) - Stores email for lookup
• usertoken:[usertoken] (eg. usertoken:XXXXXXXX - bob) - Remember Token based user lookup.
