Magento: JSON Routes

To respond to a route (assuming you have the controller set up already) with JSON:

public function foobarAction {
  $obj = getSomeObjectOrSimpleXML();
    ->setHeader('Content-Type', 'application/json', true)

Make sure you include the final parameter to setHeader. While not completely necessary, it ensures that we overwrite any previously set Content-Type.
