/*Anti-Leech script by Steve Oliver
 This is the best anti-leech out there.
 No way of telling where the file is coming from.
 Set the 2 variables below, $domain and $folder.
 You can replace the errors below where commented with html files if wanted.*/
//your domain
$domain="www.yourdomain.com";
//folder that the files are in, no lead or trailing slashes
$folder="filefolder";
$filename=stripslashes(urldecode($QUERY_STRING));
//this can be replaced with
//if ($filename==""){readfile("http://www.yourdomain.com/invalidfile.html");exit;}
if ($filename==""){die("<h1>Invalid File Request...</h1>");}
$refr=getenv("HTTP_REFERER");
list($remove,$stuff)=split('//',$refr,2);
list($home,$stuff)=split('/',$stuff,2);
//this can be replaced with
//if ($home!=$domain){readfile("http://www.yourdomain.com/leecher.html");exit;
if($home!=$domain){die("<h1>Leecher!</h1>This file is from $domain");
