title: Symfony2, loading css files without cache
body: <p>Currently i'm doing design of site based on symfony2, question is how to disable cache of css files? Now if i change something in css file - nothing changes in browser. When i try to cache:clear - still nothing.</p>
  
  <p><strong>config.yml</strong>:</p>
  
  <pre><code># Assetic Configuration
  assetic:
  debug:          "%kernel.debug%"
  use_controller: true
  #bundles:        [ ]
  #java: /usr/bin/java
  filters:
      cssrewrite: ~
      #closure:
      #    jar: "%kernel.root_dir%/Resources/java/compiler.jar"
      yui_css:
          jar: "%kernel.root_dir%/Resources/java/yuicompressor-2.4.7.jar"
  </code></pre>
  
  <p>and in <strong>twig</strong></p>
  
  <pre><code>    {% stylesheets filter="cssrewrite" output="css/general.css"
          "@EveCommonBundle/Resources/public/css/main.css" 
          "@EveCommonBundle/Resources/public/css/another.css" %}
      &lt;link rel="stylesheet" type="text/css" href="{{ asset_url }}" /&gt;
      {% endstylesheets %}
  </code></pre>
  
  <p>What must i change to get "latest" css file in browser?</p>
  
  <p>Problem is that when i change <code>@EveCommonBundle/Resources/public/css/main.css</code>, in <code>web/css</code> still remain old one (dumped by terminal), and it's not been recreated, that's why no "new changes" shows in browsers, and recreate that file i can only by terminal... how can i get sf2 recreate css files on each F5 in browser (in <code>web/css</code> folder)? </p>
