Gracefully Shutdown ASP.NET Core Web Host

[TonyValenti]

Is there a way to gracefully shutdown an ASP.NET core Web Host so that active requests are serviced and the proper content is returned to the client?

I am doing some tests and it seems like calling IHostApplicationLifetime.StopApplication() results in some clients getting The response ended prematurely. What I'd like to make sure of is that any HTTP connections are fully serviced and receive proper responses (not even 500 errors).

Any thoughts?

You could figure out whether ASP.NET or Kestrel provided a state that no longer accept new HTTP requests.

If such technique is deployed in production environment, I can see DoS attack by sending an incomplete request or not reading response.
