asps-check-referrer

Exactly what I was looking for, worked very nicely for me.

I tried every single possible way of allowing my domain name as the allowed referrer of protected pages (MyDomain.com, www.MyDomain.com, and without http), as well as my IP address, for manually-clicked links to those protected pages as well as redirects coming from within my domain... but yet still can't access protected page. I looked at the website's personal forum and there isn't anything regarding wordpress support. Think they just want you to purchase a license. Don't waste your time. Plus the only way I could even protect any pages is if I used the third option at the bottom of the settings page, of the content section. It doesn't work if you put a page in the page's section. Whether you use http, www, or just "/mypage". Nothing works.
