HTTP POST then Redirect?

I'm using the code below to post form data to an ASP script. But I need to redirect to a "thank you" page when it all done or the person filling out the form sees what they're not supposed to see. Any way I can do this? If take out the last line and print a header(URL) it won't post the data. Thanks Jeff ----------------- function http_post($host, $path, $data) {

     $http_response = '';
     $content_length = strlen($data);

     $fp = fsockopen($host, 80);
     fputs($fp, "POST $path HTTP/1.1\r\n");
     fputs($fp, "Host: $host\r\n");
     fputs($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
     fputs($fp, "Content-Length: $content_length\r\n");
     fputs($fp, "Connection: close\r\n\r\n");
     fputs($fp, $data);
     while (!feof($fp))
     {
          $http_response .= fgets($fp, 128);
     }
     fclose($fp);

     return $http_response;

} $arr = array(); foreach($_POST as $key => $value) { $arr[] = $key.'='.urlencode($value); } $data = implode('&',$arr); $http_response = http_post('www.blah.com', '/test.aspx?', "$data"); print "$http_response";
