Redirect in observer on server not working

Question

I have created an observer model to redirect the checkout page after successful order to another form. The Redirection code I have applied is working on my localhost but when I tried the same code on server it is giving the error :

 a:5:{i:0;s:140:"Cannot send headers; headers already sent in /home1/remarkc4/public_html/restauranttechpros/app/code/local/Mage/Cms/Block/Eblock.php, line 2";i:1;s:2101:"#0 /home1/remarkc4/public_html/restauranttechpros/lib/Zend/Controller/Response/Abstract.php(148): Zend_Controller_Response_Abstract->canSendHeaders(true)

Here is my code of observer:

 <?php 
 class Dataman_OrderInfo_Model_Observer
 {
 public function getSuccessOrderInfo(Varien_Event_Observer $observer)
 {
    $orderIds = $observer->getEvent()->getOrderIds();

    if (!is_array($orderIds) || (!array_key_exists(0, $orderIds))) 
    {
        return;
    }

    $order = Mage::getModel('sales/order')->load($orderIds[0]);
    $items = $order->getAllItems();
    $itemcount=count($items);        
    $ids=array();
    foreach ($items as $itemId => $item)
    {            
        $ids[]=$item->getProductId();        
    }        

    if(in_array('1207',$ids))
    {            
        Mage::app()->getResponse()->setRedirect(Mage::getUrl('customerticket'))->sendResponse();
        exit();
    }

    return true;
 }
 }
 ?> 

Please help me what am I doing wrong.

Thanks

Check these articles, but i think that the sendResponse is causing the error message :
https://stackoverflow.com/questions/13236912/magento-redirect-from-observer-that-always-works https://stackoverflow.com/questions/9749005/magento-redirect-customer-from-observer-method http://ka.lpe.sh/2013/07/21/magento-redirect-from-observer/

Than look at the server configuration (php.ini) and maybe your cookie configuration. Also check your general web configuration http://www.magentocommerce.com/wiki/modules_reference/english/mage_adminhtml/system_config/edit/web

These article lists the step required to move a production to development server. http://markshust.com/comment/117. http://www.islbd.com/resources/item/24-how-to-move-magento-from-one-server-to-another.html In your case is the other way around, but the steps are the same. In essence you need to update some config values. Pay attention to urls and cookies. I think that they are causing your headaches.

try the below code in if condition for redirection, Hope so this will work,

if(in_array('1207',$ids))
{
    $response = $observer->getResponse();
    $response->setRedirect(Mage::getUrl('customerticket'));
    Mage::app()->getFrontController()->sendResponse();
}
