Actions in CakePHP can be any public method on a controller, that is not declared in Controller. If you
want controller methods to be public and in-accessible by URL, then prefix them with a _.
For example public function _loadPosts() { } would not be accessible via URL. Private and protected methods
are also not accessible via URL.
