I have a CMS and one of my products involves submission of information after a payment to PP. I want to have the link-back from a confirmed payment on PP go directly to the submission form on my site.
I don't want people to be able to bookmark or memorize the link to the submission form and be able to bypass payment in the future.
What would be the best way to do this via the HTACCESS file so that the form page only accepts referrals directly from Paypal? If you have other suggestions to accomplish this, those would be welcomed as well, please remember this is for a Joomla CMS based site
Thanks
