restrict direct linking to AJAX pages in a certain directory

Question

I don't want to allow people to go directly to the pages in the AJAX directory but they still need to be served from their parent page. I have tried numerous .htaccess lines but they all block it from the main page as well. to sum up, I dont want people to be able to type in http://www.mysite.com/AJAX/page1.html and view it but page1.html needs to be brought into its parent page via AJAX.

<LIMIT GET POST>
Order deny, allow
deny from all
</LIMIT>

blocks all access

Can you define a flag in the parent file define('IS_IN_SCRIPT',1); and check for it in the AJAX pages? will that work with AJAX pages or only PHP includes?

Answer 1

You could always set up something so that if a particular argument isn't passed in via GET or POST, the ajax page will just redirect you elsewhere.

In php, it'd look like

if(!isset($_POST['some_var']))
  header('Location: somePage.html');
