I was so happy about my little direction script which allows me to decide on the fly to hide (use iframe 100% width and height) or not hide (simple header redirect) the destination url.. But I've seen that text on clickbank help pages, so I quickly reverted to not hiding the destination url.. " Invalid HopLinks To ensure proper tracking of your HopLink referrals, your HopLink needs to open into the top level of a new or existing window. For most affiliates, this is not a problem. However, some affiliates attempt to hide their HopLinks by having them open into other types of sub-window objects, such as frames, iframes, layers, applets, or images. These types of HopLinks are considered invalid, and can result in lost affiliate referral credit, incorrect display of your website, or, in the case of abuse of the HopLink system, could result in account termination without notice.
