echo in controller

Question

Is there a way to don't generate the layout, but write our something with echo? (Like a blank page with some text on it)

Or is there a way to get magento to not send any headers?

I have this because I would load this controller with ajax:

$this->getResponse()->clearAllHeaders();
header("Access-Control-Allow-Origin:*");

If I just simple echo some text, then I will get the following error:

Exapmle code:

  public function indexAction(){
      echo("some text");  
  }

You must use $this->getResponse()->setBody('your echo');
