        $fsp = fsockopen($host, $port, &$errno, &$errstr, 30);
        if(!$fsp){
                print "\nopen socket failed\n";
        }else{
                fwrite($fsp, "POST ".$path." HTTP/1.1\r\n");

                do{
                        if(strlen($out=fread($fsp, 1024)) == 0) break;
                        $resp .= $out;
