title: how to serve files over http2 but fetch API data over http1 in express
body: <p>i am using express in my application. i want to upgrade to http2 to serve all the static resources over http2. but i need to fetch data from 3rd party apis which may not support http2 yet so i want this connection over http1.</p>
  
  <ul>
  <li>from browser to express , the connection should be h2.(for static files)</li>
  <li>from express to third parties , connection should be h1(for data)</li>
  </ul>
  
  <p>how do i achieve this ?</p>
  
  <p>i have tried using <code>node-http-proxy</code> and <code>request</code> to make calls to third parties from express. but they are giving errors.</p>
