body: <p>How can I access a GET request in CAKEPHP ?</p>
  
  <p>If I am passing a variable in the url </p>
  
  <pre><code>http://samplesite.com/page?key1=value1&amp;key2=value2
  </code></pre>
  
  <p>Should I use $_GET or $this->params to get the values in controller?
  What is the standard in CAKEPHP ? </p>
