To disable the context menu (right-click or context key), you can use
this:
<body oncontextmenu="return false;">
See here for more info:
http://javascript.about.com/library/blnoright.htm
In addition, you can check the referrer URL which will block some
attempts to access the page by just pasting the URL in the browser.
(This can be circumvented by the user however because the referrer can
be spoofed.) Here's an example:
function checkReferrer($uriPath)
{
$from = '#^https?://' . preg_quote($_SERVER['HTTP_HOST']) .
'((?-i)' . preg_quote($uriPath) . ')$#i';
if (!isset($_SERVER['HTTP_REFERER']) ||
!preg_match($from, $_SERVER['HTTP_REFERER'])) {
die();
}
}
//
// Pass the path to your referrer script here:
//
checkReferrer('/path/to/script.php');
