title: How to disable HTTP/2 in chrome or chromium?
body: <p>I'm trying to debug difference between HTTP/1.1 and HTTP/2.
  Is there any possibility for disabling HTTP/2 in chrome or chromium?
  I couldn't find this option flag in chrome 56. I have tried chromium 58 with <a href="http://peter.sh/experiments/chromium-command-line-switches/#disable-http2" rel="noreferrer">flag <code>--disable-http2</code></a>:</p>
  
  <pre><code>./Chromium.app/Contents/MacOS/Chromium --disable-http2
  </code></pre>
  
  <p>But content is still delivered with HTTP/2 protocol after using this flag:</p>
