With the following WebHost setup (notice KeepAliveTimeout):

return WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseKestrel(x => x.Limits.KeepAliveTimeout = TimeSpan.FromSeconds(1))
                .Build();

we expect to have kestrel kill the request (given execution lasts more than 1 second) and see an error code returned. However, it seems to do nothing.

What are we missing?

KeepAliveTimeout is only for idle connections between requests, not during requests. There is no built in request timeout. – Tratcher May 15 '18 at 19:04
@Tratcher - thanks! Is there any plan to add request timeout? – steamrolla May 15 '18 at 19:17

No. The old one relied on thread abort which doesn't work in the async world. You can add a basic one by chaining the RequestAborted cancellation token and adding a timeout there. Then you need your request handling logic to register with the token. – Tratcher May 16 '18 at 01:27
