Maintain Session State Across Domains

Hello All:
I am writing an ASP.NET application that will take the user to PayPal to
make some payments. Before going to PayPal, I collect relevant user
information and store it in a session state slot. I'm using InProc session
state. After the user goes through the paypal site, the session information
I collected / saved is gone.
Is there a way to maintain state across domains without resorting to
ugliness like saving the session info to temporary files on the server, etc.
?
RobertTo my knowledge, this should not be an issue unless you are linking
application pages accross non-secure (port 80) and secure (port 443) ports o
n
your webserver. If you are linking between secure and non-secure, the sessio
n
var's will not be maintained.
For example, are you collection the session vars on a secure page, directing
to PayPal, and having PayPal redirect to a non-secure page?
Hope this helps... Rich
