I have a forum which does not respect the general conditions of use of PayPal and I created a site and buy a domain of showcase but I do not know how to make the queries go through this domain.
That would require quite some modifications. Firstly you would have to redirect from your forum to your site which handles paypal. And when the payment is successful you would have to send the update to your forum from your paypal handling site so that upgrades etc.. work automatically.
