See Emprivo's comment about detecting JavaScript redirects. You could use a similar approach to detect Meta refresh redirects, too.

Great script, it does not currently detect Meta Refresh redirects though. There are quite a few of those as well unfortunately.

If at all possible, don’t. Anti-bot measures are sometimes very sophisticated, and finding a way to fool them can take a lot of time. Is that one site really worth it?

That said, the first thing I’d suggest would be using a HTTP sniffer to check what headers a normal browser sends when opening that site, and modifying the script to send the same or similar headers. This might fool a primitive bot detector.

This is a great script. Works perfectly for most redirections I find. I’m working with one instance where the site somehow knows that this is essentially a bot testing the link and not a normal browser. I have this same problem using CURL-based solutions.

Any ideas how I can determine the final URL in a way that will fool these sites into redirecting as normal? Somehow it needs to simulate how the site handles the situation when a normal user visits the original URL. Ideas?

Nice clean script. I added a couple of lines to handle websites that connect, but take way too long to load (so you can skip them):

while(!feof($sock)) $response .= fread($sock, 8192);

becomes:

stream_set_timeout($sock, 1);
while(!feof($sock)) {
$meta = stream_get_meta_data($sock);
if ($meta['timed_out']) break;
$response .= fread($sock, 8192);
}

(set the stream timeout to whatever you want in seconds, or 0,X where X is ms)

Thanks to all, on the net, i was able to get the redirect working, with some help.. code below

I added this to the top of the code, now space or no space it works good.

$mob = str_replace(“+”, “_”, $_SERVER['QUERY_STRING']);
$url = “http://example.com/pfinder?” . “$mob”;

and at the end i added this to go to the page i want
$fin = get_final_url($url);
$mov = parse_url($fin, PHP_URL_QUERY);
sleep(5);
header(“Location: http://enample1.com?$mov“);

works fine..
But now i have a problem, the server i was to put this on does not support PHP. (server side)
I know this is not the right forum, but can any one help me to get this done in javascript (client side)
