Magento Cookie (Session)

Question

I have weird behavior in IE in my magento store with frontend (session) file file breaking. Does anyone have a clue where in the purple cookie code the frontend is set?

Thanks!

Answer 1

Afaik, the cookie 'frontend' set right before sending the current action.

Take a look at Mage_Core_Controller_Varien_Action::preDispatch() .

Session start

Looking at preDispatch() , find the line that starts the session:

  Mage::getSingleton('core/session', array('name' => $namespace))->start(); 

which usually (if not redefined) is finally displayed on

  Mage_Core_Model_Session_Abstract_Varien::start() 

This is the place where all standard session files are initialized, including cookie settings, using session_set_cookie_params .

Revalidation

Remember that as soon as a cookie already exists, the first cookie manipulation may already occur when the main session receives an instance, i.e. before calling start() . This is because the constructor calls revalidateCookie() when instantiating the main session. Cm:

  Mage_Core_Model_Session_Abstract_Varien::init()
