I have a page on my site that should only be accessed when Paypal is the referring site. What should I put in my .htaccess to make this work? I only have this much so far:
Assuming mod_access and mod_setenvif are installed, I think it should be something like this, but I have not tested it: SetEnvIfNoCase Referer "^http://www.paypal.com" block deny from env=block
