The aMember sign-up page is to be displayed as an iframe or as a link from the referring site. The aMember protected content will be free but only for members of the referring site. If you come from site A you can register. Come from anywhere else and you are rejected. Is there a method to accomplish this? I understand that Apache has a referrer restriction tool for denial or acceptance but I'm hoping there is an easier method or someone can help me with the Apache. Thanks.
