title: How symfony's asset url works?
body: <p>I'm working on one of symfony2.6 project. The purpose of this website is to load in other websites as a plugin.</p>
  
  <pre><code>{% javascripts 
  '@OfficeBrainImagePersonalizeBundle/Resources/public/js/jquery-ui.min.js'
  '@OfficeBrainImagePersonalizeBundle/Resources/public/js/intro.js'
  '@OfficeBrainImagePersonalizeBundle/Resources/public/js/enscroll.js'
  '@OfficeBrainImagePersonalizeBundle/Resources/public/js/select2.min.js'
  '@OfficeBrainImagePersonalizeBundle/Resources/public/js/pageguide.min.js'
  
   filter='uglifyjs2' %}
      &lt;script src="{{ asset_url }}" type="text/javascript"&gt;&lt;/script&gt;
  {% endjavascripts %}
  </code></pre>
  
  <p>I have used assetic bundle load load js and css. This website is opened as in a popup. So this is where the problem occurs. the js and css takes that third party website's base url. SO I don't know how this base url parts works. </p>
