I have a question about session values.
My app is using cookieless mode and session in the url. I store all the values in the session. My web app had to use payment portal for security reasons. So, I had to post the necessary user data to the portal and portal will process the payment. After that, the payment portal will return to the URL I specified with session ID.
When the user get back to the app, previous info that I store in the session are lost or asp.net won't let me retrieve it.
Is there anything that I am missing.
