示例1: redirectBack
/**
* Redirect back. Uses either the HTTP_REFERER or a manually set request-variable called
* _REDIRECT_BACK_URL.
* This variable is needed in scenarios where not HTTP-Referer is sent (
* e.g when calling a page by location.href in IE).
* If none of the two variables is available, it will redirect to the base
* URL (see {@link Director::baseURL()}).
* @uses redirect()
