We integrate with SagePay Server using ASP.Net and we seem to have a problem getting session on our NotificationUrl.
We get no information when we try to read session on the Notification page, but strangely the page we set as RedirectUrl can read all the values from session. Can you please advise if we are doing anything wrong or if we have to pass any parameter to access session information on the notification page?
Thanks,
PS: I have also posted the question on SagePay support forum
