title: Yii User-friendly url and keep the old get format working
body: <p>I set to the main config the following url rules:</p>
  
  <blockquote>
  <pre><code>    'urlManager'=&gt;array(
          'urlFormat'=&gt;'path',
          'showScriptName'=&gt;false,
          'rules'=&gt;array(
              '&lt;controller:\w+&gt;'=&gt;'&lt;controller&gt;/list',
              '&lt;controller:\w+&gt;/&lt;action:\w+&gt;'=&gt;'&lt;controller&gt;/&lt;action&gt;',
              '&lt;controller:\w+&gt;/&lt;id:\d+&gt;/&lt;title&gt;'=&gt;'&lt;controller&gt;/view',
              '&lt;controller:\w+&gt;/&lt;id:\d+&gt;'=&gt;'&lt;controller&gt;/view',
              '\?r=&lt;controller:\w+&gt;/&lt;action:\w+&gt;' =&gt; '&lt;controller&gt;/&lt;action&gt;'
          ),
      ),
  </code></pre>
  </blockquote>
  
  <p>Everything is woking fine, but I also want the previous url format to keep working so I don't have to rewrite lots of urls that I don't care it to be seo-friendly:</p>
  
  <pre><code>index.php?r=controller/action&amp;param1=value1
  </code></pre>
  
  <p>But it shows an error now. Is there a way to keep it working?</p>
