I'm hosting an ASPNET Core 1.1 app on IIS with the following settings to keep it always running
However, I see the app getting terminated time to time. Before termination I see the following in the logs
2018-03-14 17:20:53.202 [Information] Request starting HTTP/1.1 POST http://127.0.0.1:32751/myapp/iisintegration 0
2018-03-14 17:20:53.205 [Information] Request finished in 3.98ms 202
2018-03-14 17:20:53.203 [Error] Unhandled exception
System.Threading.Tasks.TaskCanceledException: A task was canceled.
The POST /iisintegration
looks interesting. Is IIS sending a command to terminate the app?
PS
After digging around IIS integration middleware , it looks like that POST
is actually IIS sending a termination command. This is the code that handles it
private static readonly PathString ANCMRequestPath = new PathString("/iisintegration");
...
// Handle shutdown from ANCM
if (HttpMethods.IsPost(httpContext.Request.Method) &&
httpContext.Request.Path.Equals(ANCMRequestPath) &&
string.Equals(ANCMShutdownEventHeaderValue, httpContext.Request.Headers[MSAspNetCoreEvent], StringComparison.OrdinalIgnoreCase))
{
// Execute shutdown task on background thread without waiting for completion
var shutdownTask = Task.Run(() => _applicationLifetime.StopApplication());
httpContext.Response.StatusCode = StatusCodes.Status202Accepted;
return;
}
So my question is: Is there a way to disable this functionality?
