Can ASP see a session variable from a ASP.NET page?

I have an Extranet that currently is created using ASP pages. I will soon start the process of updating the sites to use all ASP.NET pages since we have just installed a Windows 2003 server to handle .NET with IIS6. Meanwhile I have updated the login page to ASP.NET from ASP. This login page authenticates the user, creates a few session variables, then redirectes to the correct user site which is in ASP. The ASP page on the user site is looking for the session variables from what used to be an ASP page. It does not appear to see them. Is there a way to let a ASP page see session variables created in the ASP.NET page? I do not want to update the user's site page yet because this would cause a chain reaction of updates that I currently do not have time for yet.
