title: url management in Yii 2
body: <p>I have this url</p>
  
  <pre><code>http://example.com/index.php/controller_name/action_name?queryString=123
  </code></pre>
  
  <p>This url is working fine but when I am trying to use the queryString like in the old version of Yii </p>
  
  <pre><code>http://example.com/index.php/controller_name/action_name/queryString/123
  </code></pre>
  
  <p>I get an <strong>"unable to solve request"</strong> error.<br/></p>
  
  <p>I 've already enable prettyurl in my config file and the following url is working </p>
  
  <pre><code> http://example.com/index.php/controller_name/action_name.
  </code></pre>
  
  <p>My config looks like :<br></p>
  
  <pre><code>'urlManager' =&gt; [
          'class' =&gt; 'yii\web\UrlManager',
          'enablePrettyUrl' =&gt; true,
          'showScriptName' =&gt; false,
          'rules' =&gt; [
              '&lt;controller:\w+&gt;/&lt;id:\d+&gt;' =&gt; '&lt;controller&gt;/view',
              '&lt;controller:\w+&gt;/&lt;action:\w+&gt;/&lt;id:\d+&gt;' =&gt; '&lt;controller&gt;/&lt;action&gt;',
              '&lt;controller:\w+&gt;/&lt;action:\w+&gt;' =&gt; '&lt;controller&gt;/&lt;action&gt;',
              'module/&lt;module:\w+&gt;/&lt;controller:\w+&gt;/&lt;action:\w+&gt;' =&gt; '&lt;module&gt;/&lt;controller&gt;/&lt;action&gt;',
          ],
      ],
  </code></pre>
  
  <p>What am I missing?</p>
