Magento Session from external page (same domain)

[gademucomp]

I need to check that a user is registered and get your information, but all in a file within the same domain but outside the structure of Magento: /mymagento/logged.php\[code\]require_once ('app/Mage.php');Mage::app(); define('ROOT', Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_WEB));$sessionCustomer = Mage::getSingleton("customer/session");if($sessionCustomer->isLoggedIn()) { $customer = $sessionCustomer->getCustomer(); $telefono = $customer->getTelefonoMovil();} else { header('Location: '.ROOT.'customer/account/login/');}\[/code\]But it does not work, can not find the session. I have reviewed the following threads:

• Magento Session not working in external page (same domain)
• Magento customer/session not working
• How do I create a Magento session outside of Magento?
• How to access Magento user's session from outside Magento?
• Checking for Magento login on external page
• Get magento session variable in another page
