This script will create two hook files:
/opt/elasticbeanstalk/hooks/configdeploy/pre/99patchwsgi.py
/opt/elasticbeanstalk/hooks/appdeploy/pre/99patchwsgi.py
and will be executed during app deploy or config update.

We can put customized apache configs that must be inside VirtualHost, for example, enable_auth_header.conf,
in /etc/httpd/wsgi.conf.d directory, and the config files will be included by IncludeOptional /etc/httpd/wsgi.conf.d*.conf.

Is there a way to use this to force http => https redirects?

@djshen-ponddy can you elaborate steps how to deploy this script and will it be applicable in autoscale case?
