cakephp Supress All Headers And ALL data

I am trying to create a subscribable web cal. The file works, if I link to it directly. But when generated out of CAKEPHP, even with a blank layout, the calendar program says the data is invalid. I am guessing there are some hidden headers, data, something that cakephp is sending in the background. Any way to have cakephp just send the actual file?

Any other ideas why开发者_开发百科 I can't subscribe?

Make sure that you put Configure::Write('debug',0); in the action in your controller that returns the data for the calendar. And then make sure you call a layout that ONLY has <?php echo $content_for_layout; ?> and nothing else in it using $this->layout = ‘yourlayout’; in that same action in the controller.
