title: POST request body being lost with nginx reverse proxy
body: <p>I'm using nginx as a reverse proxy for a http service using a configuration like this:</p>
  
  <pre><code>location /jobexecutor/ {
          proxy_pass      http://jobexecutor:8080/jobexecutor/;
          proxy_set_header    Host $host;
          proxy_set_header    X-Real-IP $remote_addr;
          proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header    X-Forwarded-Proto $scheme;
          proxy_redirect      off;
          proxy_connect_timeout   75s;
  }
  </code></pre>
  
  <p>GET requests are being proxied to the service fine, but when I use POST the request is proxied to the service OK, but the body is empty. When POSTing to the service directly it works fine.
  Any ideas what's wrong?</p>
