We're running a large web application using angularjs, consuming a .NET Web API by making xhr
calls.
This works really well with Chrome/Firefox.
The application is hosted on a machine with Win2k8R2 and IIS7.5, we've been able to reproduce the same error using different authentication methods, different client operating systems (Win7,10 and browsers (IE10,11,Edge).
Unfortunatley I'm not able to include the routes but I've marked the requests in the chrome network (bottom picture) taking more than 9s in the first picture (IE10).

Is there a solution out there?
