How To Refresh Captcha On Page Reload

hi, how to show a different code in the captcha box every time a user refreshes or reloads the browser ?




					      	<div id="captchaBox" style="border-bottom: 1px solid #E2E2E2; padding-bottom:10px;">

			            		<?php $this->widget('CCaptcha', array('clickableImage' => true)); ?>

			       			 </div>    



I think you can configure CCaptchaAction::testLimit to 1 to achieve that.




public function actions()

{

	return array(

		// captcha action renders the CAPTCHA image displayed on the contact page

		'captcha'=>array(

			'testLimit' => 1,

		),

		...

	);

}
