Can I run ASP 3.0 pages side-by-side with ASP.NET pages?
Yes. But, ASP 3.0 applications are processed by the asp.dll ISAPI extension and ASP.NET pages are handled by aspnet_isapi.dll. An important consideration is that the two environments are separate. Session and Application state variables are not shared. ASP.NET and ASP 3.0 can exist side by side in a single web application. But, information must be manually passed between the two environments.
