title: IIS Node.js server download files relay error on Firefox and Chrome
body: <p>I'm using <code>IIS</code> 10 server as a gateway for Node.js server.</p>
  <p>When client calls download files such as zip file, <code>IIS</code> server download <code>Node.js</code> server internally with <code>HTTP</code> protocol, and then it pass to client with <code>HTTPS</code>.</p>
  <p>But in Chrome web browser, It shows error</p>
  <blockquote>
  <p>net::ERR_HTTP_1_1_REQUIRED with status 200, and when I try to download again it works well until I clear  the caches.</p>
  </blockquote>
  <p>In Firefox, it returns status 200 too, but nothing's happen.</p>
  <p>In Microsoft Edge and IE11 works well too.</p>
  <p>I've set enough timeout and buffer size in <code>IIS</code>.</p>
  <p>May Chrome and Firefox go wrong at <code>HTTPS</code> - <code>HTTP</code> connection or something else?</p>
