How to send Yii::app - post request via controller?

I’d like to redirect after an action is completed. But I want to do as a post request. I know in CHtml, I can use:

CHtml::link('CLICK ME","#", array("submit"=>array("controller/action", 'id'=>$model->id)));

But how do I do this in a controller?

$this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array("controller/action));

I think this is not possible as docs says


Just include the page in your controller, don’t make any request sending. I think you can not forward request in php.

It was worth a try, thanks.
