Hi Josef


I had a similar problem (using worldpay) which redirects by pulling your 
site page into its system so that the page actually comes from the 
worldpay servers and all session info is lost. I needed to recreate the 
session, recreate the basket and (sometimes) automatically log the user 
in from the worldpay domain. Wrestled with this for a loooooooooooong 
time. $GLOBALS["TSFE"]->initFEuser(); was the answer. Here is the code I 
am using. It took me such trail and error to get it right, if you spot 
any redundancy, please let me know. Hope this helps. Thank you.

      //Add basket to session
      $GLOBALS['TSFE']->fe_user->tx_commerce_basket = 
t3lib_div::makeInstance('tx_commerce_basket');
      
$GLOBALS['TSFE']->fe_user->tx_commerce_basket->set_session_id($_POST['M_s
id']);
      $GLOBALS['TSFE']->fe_user->tx_commerce_basket->load_data();

      if (!is_array($GLOBALS['TSFE']->fe_user->user)){

         $rSql = 
$GLOBALS["TYPO3_DB"]->exec_SELECTquery("*","fe_users","uid='" . 
$_POST['M_uid'] . "'");
         unset($GLOBALS['TSFE']->fe_user->user);
         if(($aUser = $GLOBALS["TYPO3_DB"]->sql_fetch_assoc($rSql)) !== 
FALSE) {
            $GLOBALS["TSFE"]->fe_user->createUserSession($aUser);
            $GLOBALS["TSFE"]->fe_user->loginSessionStarted = TRUE;
            $GLOBALS["TSFE"]->fe_user->user = 
$GLOBALS["TSFE"]->fe_user->fetchUserSession();
            $GLOBALS ["TSFE"] ->loginUser = 1;
            $GLOBALS ["TSFE"] ->fe_user->start();
            }
         }

      }

      //Init a new FEUser session on new domain based on FE_SESSION_KEY;
      $GLOBALS["TSFE"]->initFEuser();
