Hi Guys ,
I have a problem in which for some strange reason , sometimes the customer pays up in my payment gateway but he is not redirected to the checkout sucess page . There fore he is unable to get the order conf. email and I cannot see the order in the admin panel .

I wish to store all the order related info in a flat file before redirecting the customer to a third party payment gateway .. so I have the details like customer name,add,products,delivery date ..etc etc stored in a flat file before redirecting to the payment gateway . I want to know what all info is available in the Session variables and what are their names ?
