Redirect from auth backend

[roboslone -]

Hello,

I have an authentication backend, that authenticates users against a remote service using session cookie.
Mentioned cookie can expire and remote service requires users to refresh it by visiting that service's URL (https://auth-service.com/renew?...).

Cookie expiration is managed by that remote service, so my auth backend knows when cookie needs to be renewed before authenticating the user.

Is there a way to redirect user from auth backend?

Usually the login_required decorator does this kind of thing for me.
