title: Easy way to add case insensitive routing in CakePHP 2
body: <pre><code>Router::connect('/(?i:about)', array('controller' =&gt; 'pages', 'action'=&gt;'display', 'about'));
  </code></pre>
  
  <p><a href="https://groups.google.com/forum/?fromgroups#!topic/cake-php/E2Stqi9S708" rel="nofollow">used to work in CakePHP 1.2</a> but it seems to not be working in CakePHP 2.x</p>
  
  <p>The only other solution that I see is to use the options to set a regular expression that will match against the a flag in the rout, but it seems rather convoluted for something so simple:</p>
  
  <pre><code>Router::connect('/:aboutFlag', array('controller' =&gt; 'pages', 'action'=&gt;'display', 'about'),array("aboutFlag"=&gt;"[aA]bout"));
  </code></pre>
  
  <p>Is there an easier solution more akin to how it was done in cake 1.2?</p>
