title: How to set host header on the backend request in traefik
body: <p>I am trying to proxy a simple lambda function on AWS through traefik. But AWS is returning status code 403 with message "Bad Request" when tried with the proxied link. I think this is because of the Host header being passed wrongly as seen on other reverse proxies.</p>
  
  <p>I faced the same with nginx as well but this is fixed by providing the  following conf settings</p>
  
  <pre><code>proxy_set_header Host &lt;aws_hostname&gt;;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  </code></pre>
