title: In Symfony2 where is the correct place to store an app wide parameter?
body: <p>I'd like to store a few application specific values for example:</p>
  
  <ul>
  <li>a default Id number for a particular user choice if it's not set yet</li>
  <li>keys/tokens/secrets for various services API's like facebook or flickr</li>
  </ul>
  
  <p>Closest I've found so far is <a href="http://symfony.com/doc/2.0/cookbook/bundles/best_practices.html#configuration" rel="nofollow">http://symfony.com/doc/2.0/cookbook/bundles/best_practices.html#configuration</a></p>
  
  <p>If I used <code>app/config/parameters.ini</code> it would look like:</p>
  
  <pre><code>[flickr]
      callbackUrl = http://example.com/approve
      requestTokenUrl = http://www.flickr.com/services/oauth/request_token
      consumerKey = 123a1237a29b123a5541232e0279123
  
  [app]
      default_layout = 2
  </code></pre>
  
  <p>these should be available in different bundles and also in templates</p>
