My session variables do not cross between ASP and ASPX. Does anyone have a work around for this?

This functions as designed. Session Variables will not cross over between ASP and ASPX pages. ASP and ASPX function as seperate applications and when you cross over from one to another a new session is initiated and the 'old' one is closed. You are better off converting all you pages over to ASPX or you will have to recreate all your session variables when you cross over between ASP and ASPX and back.
