title: Can I mock the response of my request in chrome dev tool?
body: <p>I am debugging the frontend issue which only happened in production. I am wondering if there is any way that I can mock the response of request or mock some static file.</p>
  
  <p>For example,</p>
  
  <p>When I call xxx.com, it loads <code>index.html</code> and <code>index.html</code> loads <code>a.js</code>.
  Since chrome cache the js, is it possible that we can mock the <code>a.js</code> so that <code>index.html</code> will load the mocked <code>a.js</code>?</p>
