title: Match and remember value of HTTP header in JMeter
body: <p>There is HTTP Header Manager component, which allows to set some HTTP headers when HTTP Sampler is used.</p>
  
  <p>I need to intercept response header with certain name, remember it in some variable and use the saved value in all requests (override existing values, for example I recorded 100500 requests with HTTP Proxy and don't want to alter all requests with providing the variable expression).</p>
  
  <p>So the flow is something like below:</p>
  
  <ul>
  <li>send N requests to server</li>
  <li>in some response there is the header X</li>
  <li>send M requests</li>
  <li>send request with saved value of header X</li>
  <li>in some response value of header X changes, and subsequent requests with header X will use the new saved value</li>
  </ul>
  
  <p>Shall I create some controller for such behavior or there is something ready-to-use? didn't spot it yet.</p>
