I am using Joomla Iframe Wrapper to access a php file (books.php). The link I have create is only accessible to registered users.
However, when soneone type www.mysaplesite.com/books.php they are able to see the content of that php file even though they are not registered.
In what possible way can i restrict DIRECT access to that file/page WITHOUT Joomla.
Note: the books.php is an angularjs app.
Thank you
