 Posted: Wed 02 Aug '06 2:47 Post subject: Hotlinking Protection for Video Files?? |
 |
|
Hi,
I've saw numerous articles, and modules for apache that helps protect websites from hotlinking protection, but none of them work for windows. Can anyone tell me any modules, or programs that would help prevent hotlinking protection for video files.
I'm interested in something that changes the link transparently, and would work for apache on windows. Thanks |

| Please tell what you tried. When it works on *nix it should work on windows. |

That is a binary for Linux.
I see no source on that site for 2.2, so we cannot try to build it for Windows.
Best to contact the author.

this is a snippet not a final code!!!
yourpage.php
| Code: |
session_name('anti_hotdownload');
session_start();
if($_POST['do']==1&&$_SESSION['image'] == $_POST['code']){
echo '<a href="yourlink'>download</a>';
}
else
{
echo <<<END
<form action="yourpage.php" method="post">
<input type="hidden" name="do" value="1" />
<input type="text" name="code" /><img src="img.php" border="0" height="20" width="60" /><br />
<input type="submit" value="{$_lang['ok']}" />
</form>
END;
}
|
img.php
| Code: |
<?php
/**
* @author: James Blond, James Blond
*
* @param String $strSessionVar
* @param Array $rgBgColor
* @param Array $rgTextColor
* @param int $x
* @param int $y
* @return Image
*/
function security($strSessionVar,$rgBgColor,$rgTextColor,$x,$y){
mt_srand((double)microtime()*1000000); //Zufallszahl
$iRandVal = mt_rand(100000,999999);
$_SESSION[$strSessionVar] = $iRandVal;
$im = imagecreate($x,$y) or die("GD-stream konnte nicht gestartet werden");
$background_color = imagecolorallocate($im, $rgBgColor[0],
$rgBgColor[1],
$rgBgColor[2]);
$text_color = imagecolorallocate($im, $rgTextColor[0],
$rgTextColor[1],
$rgTextColor[2]);
imagestring($im,5,0,0,$iRandVal,$text_color);
header("Content-type: image/png");
imagepng($im);
imagedestroy($im); }
session_name('anti_hotdownload');
session_start();
security('image',array(255,255,0),array(0,0,0),60,20);
?>

| Unfortunately I do not know PHP. I have a site that runs on PHP-NUKE, and I know how to go in and make small changes... but I dont know how to implement the above file. Can you please help me... people are stealing the movies directly off of my server and hotlinking them. |

To be fullproof is the best to let download only logged-in users or use a script like that one from james.
On the server side only you can do, is using mod_rewrite, see http://www.apachelounge.com/viewtopic.php?t=19

That doesnt work for video files, because the referer information is not sent. |
