title: How to disable http2 in nginx
body: <p>due to <a href="https://openradar.appspot.com/26406397" rel="noreferrer">this</a> Safari Issue with HTTP/2 and Form POSTS I wanted to disable serving one Webpage via HTTP/2. So I just removed the "http2" from the server_name directive in corresponding nginx server block.</p>
  
  <pre><code>server {
    listen x.x.x.x:443 ssl;
    server_name xxxx;
    [...]
  }
  </code></pre>
  
  <p>But after I restarted NginX and opened the website in various browsers the HTTP/2 Protocol is still used...
  What am I doing wrong?</p>
  
  <p>My NginX version is 1.10.1</p>
