title: Reading response headers in Swagger
body: <p>I am using swagger 2.1.0. I am able to send a header in a request, thanks to <a href="https://github.com/swagger-api/swagger-ui#http-methods-and-api-" rel="nofollow">this example</a>.</p>
  
  <p>But now my question, the key which is to send with this example-call is received in a header of the previous response. How can I read the headers of the previous response, so I can extract the value to send?</p>
  
  <p>Maybe better, more simple: How can I read the headers which come with a response?</p>
