title: ASP.NET Unauthorized in Postman using IIS Express, but works in Chrome
body: <p>I am trying to test an ASP.NET Web Api locally using IIS Express. When I use Chrome and hit the url (localhost:5000/api/test, for example) the json displays fine, but when using Postman I keep getting unauthorized 401.2 when hitting the same url. The api controller has Anonymous access on the route.</p>
  
  <p>On the error message, one of the likely causes is:</p>
  
  <p><strong>Integrated authentication is enabled and the request was sent through a proxy that changed the authentication headers before they reach the Web server.</strong></p>
  
  <p>Is Postman somehow changing the headers?</p>
