Step 2 is to add the Session Token check to your task in your component, like this:

/**
 * Saves the form
 */
function save()
{
  // perform token check (prevent spoofing)
  $token	= JUtility::getToken();
  if(!JRequest::getInt($token, 0, 'post')) {
    JError::raiseError(403, 'Request Forbidden');
  }
  // go do some other stuff now
}

           $mailer->setSubject($asunto);
           $mailer->setBody($body);
           $mailer->IsHTML(0);

//cache.
Per activar la cache, important que el display estigui a false perque generi els fitxers corresponents.

==Opció 1==
class pruebaController extends JController
{	

	function display()

	{	


	$view = "prueba";

	$option = JRequest::getCmd('option');

	$cache =& JFactory::getCache($option);

	$cache->get($view, 'display');

	parent::display(true);

	}

}

==Opció 2 (recomenable)==
    function display($cachable=false)
    {
        $cachable = True;
        $document =& JFactory::getDocument();
 
        $viewType       = $document->getType();
        $viewName       = JRequest::getCmd( 'view', $this->getName() );
        $viewLayout     = JRequest::getCmd( 'layout', 'default' );
 
        $view = & $this->getView( $viewName, $viewType, '', array( 'base_path'=>$this->_basePath));
 
        // Get/Create the model
        if ($model = & $this->getModel($viewName)) {
                // Push the model into the view (as default)
                $view->setModel($model, true);
        }
 
        // Set the layout
        $view->setLayout($viewLayout);
 
        // Display the view
        if ($cachable && $viewType != 'feed') {
                global $option;
                $cache =& JFactory::getCache($option, 'view');
                $cache->get($view, 'display');
        } else {
                $view->display();
        }
    }

Per esborrar la cache quan editem:
$cache = &JFactory::getCache('com_eventlist');
$cache->clean();

//Detectar si existeix un menú pel SEO
$component	= &JComponentHelper::getComponent('com_medis');
$menu		= &JSite::getMenu();
$items		= $menu->getItems('componentid', $component->id);
