How can I allow access to the foo.html files in the .com/song/private/ subfolder for:

• a logged-in Wordpress user; or
• any referral domains (including subfolders) I add; or
• any URL on our own domain from the com/song/private folder;

For all others, the user should be redirected to the corresponding public version of the Post, which is the same html filename and structured .com/song/foo.html. (The private versions uses a different template with different custom fields for each Post.)

---

Update: Here's what I have so far:

<Limit GET POST>

 order deny,allow
 deny from all
 allow from domain.com/song/private
 allow from otherdomain.com

</Limit>

RewriteRule ^(.*)$ ../$ [NC,L]

More:

1. Will that last rewrite rule take people back to the public version, from com/song/private/foo.html to com/song/foo.html?

2. I found the following rule for detecting Wordpress logged-in status, but what do I put aferward with a RewriteRule, and will it work anyway? (If not, is there an alternative?)

   RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in_.*$

   N.B.

   • I have added code to my root .htaccess allowing me to insert additional .htaccess files in other subfolders as needed.

   • Copied from Stack Overflow, where they suggested I ask here.
