We are using a public apache web server as a reverse proxy for to show a drupal instance (to the client). The website should come up in http://publicSite/path The Reverse proxy contains basic apache configuration pointing a "subfolder" to the internal webserver. Something like:
ProxyPass /path http://internaldomain/ ProxyPassReverse /path http://internaldomain/
The problem is that Drupal 8 has no longer a $base_url and the site is broke (CSS, JS). Adding publicSite in the $settings['file_public_base_url'] does not help. CSS/JS and links to themes are still broken.
There is a settings section on a Reverse Proxy in the settings.php, but it does not address the issue on accessing the website from a /subfolder url. Any hints to solve this issue!?
