Privatelink.de uses the double-forward strategy to make the anonymous forwarding possible. The advantages of different types of forwarding are put together here. The user is forwarded twice. At the first, the transferred information on the referring page will be deleted (referer header will be empty). Some browser still continue to send this information. Therefore, in the second step we will check whether the deletion has worked. If it is not the case, we will further use the Iframe redirection. Otherwise, users will be simply forwarded to the target page with a quick header redirection.
