Session variable is not transferred to an asp page?

I have a asp.net project with all major pages written in aspx, but I want to keep an existing asp page in the same directory as the aspx files. But when the asp page gets loaded, the session variable is not recognized. Is this the case and why?To be specific, when I load the asp.net app using the address of http://localhost/myproj/ it works fine, and the asp page could read the session variable assigned by an aspx page. But if I use my computer name, say http://keystrokes_win2k/myproj/ then it doesn't work.

Any ideas?
No, the ASP and ASP.NET sessions are two separate objects that do not share their data. There are some third party session objects that you can use to communicate between the two environments, though.
What is the third party session object, please provide some lead ?
