I have implemented a paypal Express Checkout for digital goods on my django application.

Everything works perfectly on chrome and firefox. however on IE10 , everything works until paypal calls my return\_url. for some reason it lose its session and direct me to a login-page because of how django registartion works. ( U use required\_login decorator)

Looking deeper, I figured that on the return\_url there is no sessionId cookie. I have no clue how any why does it happens, because it does work on firefox and chrome..
