What happens after you succesfully authenticated user, is controlled by
location where your 'auth_request' directive is written.

In example config, it contains:

location / {
    auth_request /auth-proxy;

    error_page 401 =200 /login;

    proxy_pass http://backend/;
}

i.e. users request is passed to an upstream (backend-sample-app.py application).

If you want instead of proxying, return some redirect (and probably set some
headers with data obtained from authentication), you have to setup nginx
to do it, using appropriate directives.
