Can you run ASP.NET Core 2.x MVC on Abyss as install or portable?
Run your ASP.NET Core 2.x Web application using Kesterel. It will be available locally on
http://localhost:5000.
Next configure Abyss Web Server to act as a reverse proxy to port 5000 and remote IP 127.0.0.1. This is similar to the instruction to get Tomcat or similar Web application servers to run behind Abyss Web Server:
