Session variables - ASP Classic, ASP.NET

Issue concerning keeping session across different platforms.

[9thsign]

I have a payroll application that is written in ASP classic. I will be moving to Web Services, but I'm not sure what type of front end I will use (.NET, JSP, Coldfusion). The problem is that I need to have as little downtime as possible and need to start writing the new projects in that new architecture. I can run ASP.NET and ASP classic on the same application but then I'm worried about sessions. Does anyone know how to keep session on the same website when going from an ASP classic page to an ASP.NET page(or vice versa)?
I don't want to use hidden form variables to reset session variables, I do that with ColdFusion and ASP on another app..

Thanks

ASP and ASP.NET store session info entirely differently. There is no way to share the session info.

Maybe not directly but I'm sure there's a way to create a kind of "bridge" or custom DLL or something - point is that there's always a way. I just haven't found it yet, I thought someone else might have run into this issue, or something similar.
