Zend_Session_Validator_HttpUserAgent -- need a use case

inazuma · #1 (**permalink**) 01-08-2008, 07:30 PM

Does anyone have an example or even a use case for Zend_Session_Validator_HttpUserAgent

I can't seem to get this to work even in it's most basic form.

bootstrap file:

PHP Code:


			
$session = array(
    'name'                  =>  $config->application->name,
    'save_path'             =>  $cwd.DIRECTORY_SEPARATOR.'tmp'.DIRECTORY_SEPARATOR.'sessions',
    'use_only_cookies'      =>  'on',
    'remember_me_seconds'   =>  60
);
Zend_Session::setOptions($session);
try 
{
    Zend_Session::start();
} 
catch (Zend_Session_Exception $e) 
{
    Zend_Debug::dump($e, 'error');
    die;
}
Zend_Session::registerValidator(new Zend_Session_Validator_HttpUserAgent());

....

To test the HTTP user agent change, I use the "change browser identification" tool in Konqueror

I've tried putting the Zend_Session::registerValidator(.... at different positions.

But regardless...

I can't seem to get Zend_Session to throw the error as stated in the
Zend_Session --> _processValidators() function when the user agent has changed.

Zend_Session:

PHP Code:


			
    /**
     * _processValidator() - internal function that is called in the existence of VALID metadata
     *
     * @throws Zend_Session_Exception
     * @return void
     */
    private static function _processValidators()
    {
        if (count($_SESSION['__ZF']['VALID']) > 0) {
            /**
             * @see Zend_Loader
             */
            require_once 'Zend/Loader.php';
        }

        foreach ($_SESSION['__ZF']['VALID'] as $validator_name => $valid_data) {
            Zend_Loader::loadClass($validator_name);
            $validator = new $validator_name;
            if ($validator->validate() === false) {
                throw new Zend_Session_Exception("This session is not valid according to {$validator_name}.");
            }
        }
    }

My goal here is to catch when the user agent has changed in mid session for logging.

Any ideas??
