title: Puppeteer: How to listen to a specific response?
body: <p>I'm tinkering with the headless chrome node api called <code>puppeteer</code>.</p>
  <p>I'm wondering how to listen to a specific request response and how to act in consequence.</p>
  <p>I have look at events <code>requestfinish</code> and <code>response</code> but it gives me <strong>all</strong> the request/responses already performed in the page.</p>
  <p>How can I achieve commented behaviour?</p>
