You might want to pass a status code along with $this->redirect(...). See:

/**
  * Forwards the request to another action and / or controller.
  *
  * NOTE: This method only supports web requests and will thrown an 
exception
  * if used with other request types.
  *
  * @param string $actionName Name of the action to forward to
  * @param string $controllerName Unqualified object name of the 
controller to forward to. If not specified, the current controller is used.
  * @param string $extensionName Name of the extension containing the 
controller to forward to. If not specified, the current extension is 
assumed.
  * @param Tx_Extbase_MVC_Controller_Arguments $arguments Arguments to 
pass to the target action
  * @param integer $pageUid Target page uid. If NULL, the current page 
uid is used
  * @param integer $delay (optional) The delay in seconds. Default is no 
delay.
  * @param integer $statusCode (optional) The HTTP status code for the 
redirect. Default is "303 See Other"
  * @return void
  * @throws Tx_Extbase_MVC_Exception_UnsupportedRequestType If the 
request is not a web request
  * @throws Tx_Extbase_MVC_Exception_StopAction
  * @api
  */
protected function redirect($actionName, $controllerName = NULL, 
$extensionName = NULL, array $arguments = NULL, $pageUid = NULL, $delay 
= 0, $statusCode = 303) {
}
