title: Enable Postman client side cache
body: <p>I am having issues testing cache for some of our API's through Postman App.</p>
  
  <p>I have disabled "Send nocache header", but all request are still hitting the server. I have testet both against localhost:4561(IISExpress) and our test environment. I have also tested with a custom HttpClient, which worked fine. Why will Postman not serve from cache?</p>
