You could try to access referer data $_SERVER['HTTP_REFERER']; and block if it isn´t your dns.. Not all clients sends this though...
Try this: Place this at the top of your page: <script language=" JavaScript" > <!-- function LoadOnce() { window.location.reload(); } //--> </script> Code (markup): Then change your <Body> to say; <Body onLoad=" LoadOnce()" > Code (markup):
Put this anywhere between your <head> & </head> tags: <script language="JavaScript">if(top !=self)top.location=self.location;</script> HTML: And you're done. Now when your visitors are visiting your site in an iframe, your site will break out of frames and redirect the whole browser to your page.
