How can I load CSS files located outside the web root from within a custom module?

Question

I need to store my css files at a location outside Drupal's path (e.g. /srv/assets/css/my_site/general.css). I attempt to achieve this using drupal_add_css but the browser loads them from:

http://www.my-site.com/srv/assets/css/my_site/general.css which results of course in 404 error.

Any idea how to load those external (file system) CSS files from within a module? note: I am using Linux.

drupal_add_css() expects a path relative to the site root. As such, if you're going to use drupal_add_css() you need to add a path within webroot to access the file.

One way to that is to use a symlink. For example

ln -s /srv/assets/css/my_site/general.css sites/all/modules/my_module/css/general.css

As long as the file is readable by your web server, you can use drupal_add_css to reference your symlink path.

drupal_add_css(drupal_get_path('module', 'custom') . '/general/custom.css', array('type' => 'file'));
