body: <p>How to make multiple pattern in single Symfony routing?</p>
  
  <p>Normally we have a routing as </p>
  
  <pre><code>blog:
      pattern:   /
      defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }
  </code></pre>
  
  <p>Is it possible to have two routing patterns? </p>
  
  <p>Something like </p>
  
  <pre><code>blog:
      #Below pattern to match with '/' or '/index'    
      pattern:   {/ , /index}  
      defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }
  </code></pre>
