## Enabling default_redirect_uri behaviour
For many linked-data platforms, there will be multiple authentication providers, and potential multiple client-side apps/websites. In this case it can be difficult to know where to redirect the user. On login it's possible to set `next` as a query parameter pointing to the new site, but the user may have come from sources without this parameter set (e.g. a forgot password link in an email). For user experience, we offer a system which keeps track of the location the user previously logged in from, and falls back onto this if there is not a `next` specified in the URL. To use system this simply add the following to your
LOGIN_REDIRECT_URL = '/redirect-default/'
