Can ASP and ASP.NET coexist on the same Web server?
Yes. However, they are executed as different, non-communicating processes. A Web application within a site can contain both ASP.NET pages and ASP pages. This offers some advantages if you need to move a large, functionally disjointed and rapidly changing site to ASP.NET one piece at a time. You can upgrade different sections of the application that do not depend on each other to ASP.NET, and they can coexist with the rest of the application. If you are transitioning to ASP.NET as a long-term strategy, you should use this opportunity to make as many architectural and design improvements as you can.
