    vds-3-ru - самое то будет. Только придется оптимизировать вам вдс. Если с панелью, то вам обязательно нужен будет апач. :)


    Вынужден покинуть вас. Дела на хостинге. В тикеты напишите. Там все уточнят и помогут. :)

    Ну, у нас можете взять. Адрес хостинга в личку скинул. Знания потребуются, конечно, для настройки вдс. Но если возникнут вопросы, то в тикеты напишите. Начиная с тарифа вдс-2-ру, панель лайт - бесплатно. :)

    Kylaksizov, нет. Именно фильтрацию.

    Пример кода. Переделаете под себя:

    class XssFilter extends CFilter

{



        public  $clean = 'all';       



        protected function preFilter($filterChain)

        {              

                $this->clean  = trim(strtoupper($this->clean));

                $data = array(

                         'GET'    => &$_GET,

                         'POST'   => &$_POST,

                         'COOKIE' => &$_COOKIE,

                         'FILES'  => &$_FILES

                );

                

                if($this->clean === 'ALL' || $this->clean === '*')

                {                        

                        $this->clean = 'GET,POST,COOKIE,FILES';

                }



                $dataForClean = split(',',$this->clean);

                if(count($dataForClean))

                {                 

                        foreach ($dataForClean as $key => $value)

                        {                 

                                if(isset ($data[$value]) && count($data[$value]))

                                {

                                        $this->doXssClean($data[$value]);

                                }

                        }

                }



              return true;

        }

        



        protected function postFilter($filterChain)

        {

                // logic being applied after the action is executed

        }





        private function doXssClean(&$data)

        {

                if(is_array($data) && count($data))

                {                       

                       foreach($data as $k => $v)

                       {

                               $data[$k] = $this->doXssClean($v);

                       }

                       return $data;

                }



                if(trim($data) === '')

                {

                        return $data;

                }



                // xss            

                $data = str_replace(array('&','<','>'), array('&','<','>'), $data);

                $data = preg_replace('/(&#*w+)[x00-x20]+;/u', '$1;', $data);

                $data = preg_replace('/(&#x*[0-9A-F]+);*/iu', '$1;', $data);

                $data = html_entity_decode($data, ENT_COMPAT, 'UTF-8');

                // Remove any attribute starting with "on" or xmlns

                $data = preg_replace('#(<[^>]+?[x00-x20"'])(?:on|xmlns)[^>]*+>#iu', '$1>', $data);

                // Remove javascript: and vbscript: protocols

                $data = preg_replace('#([a-z]*)[x00-x20]*=[x00-x20]*([`'"]*)[x00-x20]*j[x00-x20]*a[x00-x20]*v[x00-x20]*a[x00-x20]*s[x00-x20]*c[x00-x20]*r[x00-x20]*i[x00-x20]*p[x00-x20]*t[x00-x20]*:#iu', '$1=$2nojavascript...', $data);

                do

                {

                }

                while ($old_data !== $data);                

                return $data;

        }



}

?>

    Дальше я уже завтра поищу уязвимости.
