title: In POSTMAN how do i get substring of response header item?
body: <p>I am using postman to get response header value like below:</p>
  
  <pre><code>var data = postman.getResponseHeader("Location") . //value is "http://aaa/bbb" for example 
  </code></pre>
  
  <p>I can print the value via <code>console.log(data)</code> easily. </p>
  
  <p>However, what I really want is "bbb". So I need some <code>substring()</code> type of function. And apparently 'data' is not a javascript string type, because <code>data.substring(10)</code> for example always return null.</p>
  
  <p>Does anyone what i need to do in this case? </p>
  
  <p>If any postman API doc existing that explains this?</p>
