title: symfony link to change language and stay on the page
body: <p>I would like to make a link the will be in the layout to change the language. So it should work for many routes.</p>
  
  <p>for example
  i'm on the page /en/myModule</p>
  
  <p>and the links should point to
  /de/myModule
  /fr/myModule</p>
  
  <p>I found a solution here :http://oldforum.symfony-project.org/index.php/m/70452/</p>
  
  <pre><code>&lt;?php echo link_to(
    'Germany', 
    '@default?' . http_build_query(array(
      'sf_culture' =&gt; 'de', 
      'module' =&gt; $sf_request-&gt;getParameter('module'), 
      'action' =&gt; $sf_request-&gt;getParameter('action'))
    ), null, '&amp;')) ?&gt;
  </code></pre>
  
  <p>Problem is that I need a default route, and I don't want to have it.</p>
  
  <p>Is there any solution for what I need ?</p>
