Can't get assetic to cssrewrite prod images properly

Question

Using Symfony and Assetic I cannot get css images to 'dump' correctly in my prod environment. They continue to link back to the web/bundle/...etc.. location.

I have a very basic cssrewrite setup:

# Assetic Configuration
assetic:
    debug:          "%kernel.debug%"
    use_controller: false
    filters:
        cssrewrite:
        #closure:
        #    jar: "%kernel.root_dir%/Resources/java/compiler.jar"
        #yui_css:
        #    jar: "%kernel.root_dir%/Resources/java/yuicompressor-2.4.7.jar"

My template:

{% stylesheets 'bundles/<my bundle>/css/style.css' filter='cssrewrite' %}
    <link rel="stylesheet" href="{{ asset_url }}">
{% endstylesheets %}

I have the prod version of app.php in place with debug false:

use Symfony\Component\ClassLoader\ApcClassLoader;
use Symfony\Component\HttpFoundation\Request;

$loader = require_once __DIR__.'/../app/bootstrap.php.cache';

// Use APC for autoloading to improve performance.
// Change 'sf2' to a unique prefix in order to prevent cache key conflicts
// with other applications also using APC.
/*
$apcLoader = new ApcClassLoader('sf2', $loader);
$loader->unregister();
$apcLoader->register(true);
*/

require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/AppCache.php';

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);

// When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter
//Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

I have done:

app/console assets:install --symlink

All seems fine

Then I clear the prod cache

OK

app/console assetic:dump --env=prod

My css and js copy out with the expected file names, however I still have url('../../bundle/..etc../images/bg.png'); appearing in my css

In the symlinked version the css is: url('../images/bg.png');

So it must be something to do with assetic.

What I expect is for the 'dump'ed css to contain links like url('../images/bg.png');

And for the images themselves to be copied out to web/images/123abc.png

Should I expect this from assetic and if so what am I doing wrong?

Thanks, in advance.

It looks like you need to have relative links in your css or else assetic won't rewrite the images. Can anyone confirm if this is what I should expect? — Henry
I have reviewed the documentation and it does in fact state that this is the case. I'm seriously face-palming myself for not seeing this earlier. — Henry

// In Config.yml file 

# Assetic Configuration 
assetic:
    debug:          "%kernel.debug%"
    use_controller: false
    bundles:        [ ]

In app.php file

//If it is in dev environment In your app_dev.php file contain like this
$kernel = new AppKernel('prod', true);
$kernel->loadClassCache();

// If it is in prod environment, In your app.php file contain like this 
$kernel = new AppKernel('prod', true);
$kernel->loadClassCache();
