Python-social-auth requires real hostname when using apache+gunicorn

After a successful authentication using google-oauth2 with the python-social-auth tool, the client gets redirected to a ../complete/ page. However, after forwarding all non-static traffic from the apache to a local gunicorn server, the redirection url points to http://localhost:8000/complete rather than to the real website. This can be easily fixed by enabling the ProxyPreserveHost setting in the apache config:

<VirtualHost *:80>
        ServerAdmin ...
        ServerName ...
 
        Alias /static /.../static
 
        DocumentRoot ...
 
        <Directory ...>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
 
        ProxyPreserveHost on
 
        RewriteEngine on
        RewriteRule ^/static/.* - [L]
 
        # Django is run via gunicorn. So proxy the rest.
        RewriteRule ^(.*) http://localhost:8000$1 [P]
</VirtualHost>

Supervisord at 100% load for gunicorn

Starting a gunicorn django server with the supervisord daemon using the deprecated gunicorn_django command works but results in 100% load of the supervisor process.

[program:gunicorn]
command=start_gunicorn.sh
process_name=gunicorn  ; process_name expr (default %(program_name)s)
numprocs=1                    ; number of processes copies to start (def 1)
directory=/home/gunicorn  ; directory to cwd to before exec (def no cwd)
autostart=true                ; start at supervisord start (default: true)
autorestart=true        ; whether/when to restart (default: unexpected)
user=gunicorn                   ; setuid to this UNIX account to run the program
redirect_stderr=true          ; redirect proc stderr to stdout (default false)

After adding gunicorn to the INSTALLED_APPS in the project settings, the gunicorn server can be easily started with the python manage.py run_gunicorn command and everything works fine.
INSTALLED_APPS = (
    ...
    'gunicorn'
    ...
)
