Comment:

 the solution is just load widget rss when the requester is the client
 so i change line

 {{{
 register_widget('WP_Widget_RSS');
 }}}

 with

 {{{
 if($_SERVER['SERVER_ADDR']!=determineIP()){
                 register_widget('WP_Widget_RSS');
 }
 function determineIP() {
    if (checkIP($_SERVER["HTTP_CLIENT_IP"])) {
        return $_SERVER["HTTP_CLIENT_IP"];
    }
    foreach (explode(",",$_SERVER["HTTP_X_FORWARDED_FOR"]) as $ip) {
        if (checkIP(trim($ip))) {
            return $ip;
        }
    }
    if (checkIP($_SERVER["HTTP_X_FORWARDED"])) {
        return $_SERVER["HTTP_X_FORWARDED"];
    } elseif (checkIP($_SERVER["HTTP_X_CLUSTER_CLIENT_IP"])) {
        return $_SERVER["HTTP_X_CLUSTER_CLIENT_IP"];
    } elseif (checkIP($_SERVER["HTTP_FORWARDED_FOR"])) {
        return $_SERVER["HTTP_FORWARDED_FOR"];
    } elseif (checkIP($_SERVER["HTTP_FORWARDED"])) {
        return $_SERVER["HTTP_FORWARDED"];
    } else {
        return $_SERVER["REMOTE_ADDR"];
    }
 }

 /* BOB: By Grant Burton @ BURTONTECH.COM (11-30-2008): IP-Proxy-Cluster
 Fix */
 function checkIP($ip) {
    if (!empty($ip) && ip2long($ip)!=-1 && ip2long($ip)!=false) {
        $private_ips = array (
        array('0.0.0.0','2.255.255.255'),
        array('10.0.0.0','10.255.255.255'),
        array('127.0.0.0','127.255.255.255'),
        array('169.254.0.0','169.254.255.255'),
        array('172.16.0.0','172.31.255.255'),
        array('192.0.2.0','192.0.2.255'),

        array('255.255.255.0','255.255.255.255')
        );

        foreach ($private_ips as $r) {
            $min = ip2long($r[0]);
            $max = ip2long($r[1]);
            if ((ip2long($ip) >= $min) && (ip2long($ip) <= $max)) return
 false;
        }
        return true;
    } else {
        return false;
    }
 }
 }}}
