[fw-auth] Zend_Session_Validator Problem

Hi all,     I want to authenticate session, I found new vaildator in 1.8 . I tried to implement that so I have added code below to my bootstrap.php file. protected function _initSessionCheck()     {         /** Register Session Validator for Validation purpose */         Zend_Session::registerValidator(new My_Session_Validate());     } Now My_Session_Validate class is in file library/My/Session/Validate.php <?php class My_Session_Validate implements Zend_Session_Validator_Interface {     /**      * Setup() - this method will store the environment variables      * necessary to be able to validate against in future requests.      *      * @return void      */     public function setup()     {         //Zend_Debug::dump($_SERVER);     }     /**      * Validate() - this method will be called at the beginning of      * every session to determine if the current environment matches      * that which was store in the setup() procedure.      *      * @return boolean      */     public function validate()     {         Zend_Debug::dump($_SERVER);     } } ?> Here setup method has been called every time when request go to server, but validate method doesnt called any single time. I havent put my validation code here, I want to check that does validate method is called or not? Waiting for Quick Replay, Thanks, Dhaval
