Keeping Session Alive

[econner]

I am using a function to send POST information to a script on another server. I need to get the html of the page that results, but there is a problem. When the information is submitted on the other server, it is processed and then redirected to a different page. My problem is that my function only returns the redirect page with the header location pointing to the page that I need the info from. Roughly:
HTTP/1.1 302 Moved Temporarily Date: Thu, 14 Jul 2005 02:17:33 GMT Server: Apache/2.0.46 (Red Hat) Set-Cookie: JSESSIONID=1E23F1B83822230D32E378D2B5F9A0FA; Path=/ P3P: CP="CAO DSP DEVa TAIa OUR BUS UNI STA" Location: http://www.macwarehouse.co.uk/ec/search-result-groups.jtp Content-Length: 0 Connection: close Content-Type: text/plain; charset=UTF-8

Here is my post function:

function HTTP_Post($URL,$data, $referrer="") 
{
       // parsing the given URL
       $URL_Info=parse_url($URL);

   // Building referrer
   if($referrer=="") // if not given use this script as referrer
     $referrer=$_SERVER["SCRIPT_URI"];

   // making string from $data
   foreach($data as $key=>$value)
     $values[]="$key=".urlencode($value);
   $data_string=implode("&",$values);

   // Find out which port is needed - if not given use standard (=80)
   if(!isset($URL_Info["port"]))
     $URL_Info["port"]=80;

   // building POST-request:
   $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";
   $request.="Host: ".$URL_Info["host"]."\n";
   $request.="Referer: $referer\n";
   $request.="Content-type: application/x-www-form-urlencoded\n";
   $request.="Content-length: ".strlen($data_string)."\n";
   $request.="Connection: close\n";
   $request.="\n";
   $request.=$data_string."\n";

   $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
   fputs($fp, $request);
   while(!feof($fp)) {
       $result .= fgets($fp, 128);
   }
   fclose($fp);

   return $result;
}

You could read the Location: header in the response, and send a POST request to that. It's what any http client is expected to do.

If you've got the cURL extension, that already has such behaviour built in, if I recall.

I was attempting to do that, but what info would I send? I was trying to send a request immediately after receiving the other one, but it does not seem to go through. Can you help? Thanks!!
