I want to host multiple Rails apps on a multiple server using sub-directories. And have encountered some relative path problems.

I have made a symbolic link to the app's public directory and placed it in the /var/www/html directory,

var/www/html/
            /test_app (symbolic link to the public folder of test_app) 

and set apache as so

   LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.12/ext/apache2/mod_passenger.so
   PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.12
   PassengerRuby /usr/local/bin/ruby

   <VirtualHost *:80>
      ServerName  test.com
      DocumentRoot /var/www/html

      Options Indexes FollowSymLinks -MultiViews

      RailsBaseURI /test_app

      </Location>
   </VirtualHost>

The links in the app itself works just fine, all the links acknowledge the test_app/ directory and work, however, when it comes to showing images in the public directory in the view, the relative path goes wrong.

Say I have

/system/files/1/aaa.png

it goes looking for it in

/var/www/html/system/files/1/aaa.png

rather than

/var/www/html/test_app/system/files/1/aaa.png

As far as I understand this is an Apache setting problem than something to be done in Rails, if its possible I would prefer to have it contained in the conf file of apache rather than having to alter the code.
