Magento 1.9 redirect customer after registration

I would like to redirect all customers to a custom page after successful registration in Magento 1.9.

I have tried many things. Firstly, I am successfully overriding the core customer account controller.

I have attempted to customize the following actions:

• createPostAction
• _successProcessRegistration
• _welcomeCustomer

By trying to set redirect url or by setting BeforeAuthUrl

    //$successUrl = $this->_getUrl('*/*/index', array('_secure' => true));
    $successUrl = $this->_getUrl('*/*/success');
    $this->_getSession()->setBeforeAuthUrl('http://test.local/customer/account/success/');
    if ($this->_getSession()->getBeforeAuthUrl()) {
        $successUrl = $this->_getSession()->getBeforeAuthUrl(true);
    }
    return $successUrl;

Please note at this point, $successUrl is correct when it returns here. I see there are some post Dispatch methods that I am assuming are destorying this url and always returning to customer/account/index.

I have read several posts on this topic and cannot find a definitive answer that solves this question.

I have even set hidden form element 'success_url' in attempts to follow steps presented elsewhere as solutions to this.

What is the full, correct process that one needs to follow in order to be able to show a one time registration success page?

if you want to do this for customer successfully then you can do this using event observer

after customer successfully magento trigger an event customer_register_success

This call an observer which will reequestion to custtom page

  Mage::app()->getResponse()->setRedirct($Yourdreicurll);

Step1: create config.xml is app/code/community/Amit/Custommodule/etc/

<?xml version="1.0" ?>
<config>
    <modules>
        <Amit_Custommodule>
            <version>1.0.0</version>
        </Amit_Custommodule>
    </modules>
    <global>
        <models>
            <custommodule>
                <class>Amit_Custommodule_Model</class>
            </custommodule>
        </models>
    </global>
    <frontend>
      <events>
          <customer_register_success>
        <observers>
          <notify_user>
            <class>custommodule/observer</class>
            <method>myredirection</method>
          </notify_user>
        </observers>
          </customer_register_success>     
        </events>
    </frontend>
</config>

Step2:

create module control file Module name as Amit_Custommodule.xml at app/etc/modules/

it code is

<?xml version="1.0"?>
<config>
    <modules>
        <Amit_Custommodule>
            <codePool>community</codePool>
            <active>true</active>
        </Amit_Custommodule>
    </modules>
</config>

Step3:

Create observer.php at Amit>Custommodule>Model

code is

 <?php
    class Amit_Custommodule_Model_Observer {
        public function myredirection(Varien_Event_Observer $observer) {
        $AccountController = $observer->getEvent()->getAccountController();

        $Customer = $observer->getEvent()->getCustomer();
        
         $response1 = Mage::app()->getResponse(); // observers have event args

            $url = 'http://www.example.com/';
            $response1->setRedirect($url);
            Mage::app()->getFrontController()->sendResponse();

        return;
      }
    }
