Rails relative_url doesnt adjust links

Question

After failed attempts with Passenger (see my other question), I managed to get rails running via a reverse proxy in a subfolder. I added the lines

config.relative_url_root = "/App"
config.action_controller.relative_url_root = "/App"

to my environment. Now I can access my rails project under www.mySite.com/App. The problem is that the links /paths dont add the prefix "/App". So a link to "users" looks like www.mySite.com/users instead of www.mySite.com/App/users. How can I change this?

At least according to http://edgeguides.rubyonrails.org/configuring.html#deploy-to-a-subdirectory-relative-url-root I did everything correct.

I got it working by adjusting my reverse proxy and my rails config as follows. This is my corresponding apache file:

<VirtualHost *:80>
DocumentRoot /path/to/App/public
ProxyPass /App http://127.0.0.1:9292/App
ProxyPassReverse /App http://127.0.0.1:9292/App
</VirtualHost>

My config.ru looks like this:

require ::File.expand_path('../config/environment',  __FILE__)
map '/App' do
  run Rails.application
end

The mentioned environments variables are set in /config/environment.rb. I am not sure if they are still needed:

config.relative_url_root = "/App"
config.action_controller.relative_url_root = "/App"
ENV['RAILS_RELATIVE_URL_ROOT']  = "/App"
ENV['ROOT_URL']  = "/App"
