title: CakePHP, GET Parameters and routing
body: <p>I am fairly new to cakephp but I have a question relating to urls and parameters. I would like to be able to have a url that looks like a standard url e.g:</p>
  
  <pre><code>http://www.mysite.com/controller/myaction?arg=value&amp;arg2=val
  </code></pre>
  
  <p>I would like that url to map to an action in my controller as follows:</p>
  
  <pre><code>function myaction($arg = null, $arg2 = null)
  {
     // do work
  }
  </code></pre>
  
  <p>I realize that cakephp has routing as described <a href="http://book.cakephp.org/view/46/Routes-Configuration">here</a>, however, honestly this seems over engineered and results in a url string that is nonstandard. </p>
  
  <p>In my current situation the url is being generated and invoked by an external (billing) system that knows nothing about cake and doesn't support the cake url format.</p>
