class Zend_Controller_Request_Http 
{
    /**
     * @throws Zend_Controller_Request_Exception
     */
    public function getHeader($header)
    {
        if (empty($header)) {
            throw new Zend_Controller_Request_Exception('An HTTP header name is required');
        }

        ...
    }
    
    ...
}

Developer:

1
$request->getHeader('Origin');

IDE:

1
(!) Unhandled Zend_Controller_Request_Exception

Why should I handle the exception if KNOW that it will never happen?

Why should I suffer?
