Asp.net Web Api stop using ARRAffinity cookie

Question

My API uses bearer token for authentication and the controller use Authorize attribute.

Whenever I query the API using postman. It for some reason sends a ARRAffinity cookie with every request along with the bearer token.

However, when I call the same API endpoint with fiddler without he cookie. It fails with a 401 Randomly. YES Randomly some requests would get 200 success and some would fail with 401.

However, when I pass the ARRAffinity cookie via fidler. It works without any failure.

Is there a way to stop Web Api or azure from generating the ARRAffinity cookie. I just want to use bearer and not the cookie.
