Hi,

I don't think that you can do this directly. A workaround might help.

One might be to use a redirector script in your links that first checks if the referer points to your site and then to redirect or to add code in your pages that checks the referer. If the referer is empty or points to another site you can then redirect to the index page or wherever. Doing so would make copying links useless.

Hi,

the following snipplet is a very very basic one but it would check if the page one called has been requested by clicking on a link of a page previously sent by the same server:

Assuming that the script has the name redirect.wml and you call it with e.g. redirect.wml?tgt=urlencode("http://www.google.com") or something like that. If you even don't want the users to see the urlencoded tgt you could encrypt the target with e.g. mcrypt, convert that into a string to be used as get parameter, and decrypt it afterwards in the referer.wml script.

<?PHP
if (strstr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST'])) {
    header("Location: ".urldecode($_GET['tgt']));
} else {
    header("Location: index.wml");
}
?>

If you put

if (!strstr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST'])) {
    header("Location: index.wml");
}

in all scripts you don't want to be requested directly these scripts would redirect to index.wml if someone requests the pages directly.
