How to redirect to previous page in admin?

Question

In my admin controller action I want to redirect to the previous page. How can I do this?

Answer 1

Try this:

$this->_redirectReferer();

it does a little more than redirect to the previous page. If you specify in the url a parameter uenc it will consider that as the referrer.

Answer 2

Try this code :

 Mage::app()->getResponse()->setRedirect($_SERVER['HTTP_REFERER']);
        Mage::app()->getResponse()->sendResponse();
            exit;
