title: Upload large files failed when using nginx and zuul
body: <p>I deployed a nginx in the frontend, and zuul gateway for transfer.</p>
  <p>When I try to post a file larger than 100MB, nginx returns 504 after about 5m24s, while the zuul gateway is still transferring the data to the microservice.</p>
  <p>I tried the /zuul mode, got the same results.</p>
  <p>If post the file directly to zuul, it succeededs, as I have adjusted the zuul related parameters.</p>
  <p>I found many ways to change the delay time for nginx, for instance, in nginx.conf</p>
  <pre><code>proxy_connect_timeout 600s;
  proxy_send_timeout 600s;
  proxy_read_timeout 600s;
  send_timeout 600s;
  </code></pre>
  <p>Tried all, none of them worked.</p>
  <p>So, did I miss something or is there another solution to my problem?</p>
