title: nginx reverse proxy images and css are not loaded
body: <p>I try to configure an nginx reverse proxy to access a Jenkins instance. I can open the authentication page but there is no CSS and no image. It works perfectly when direct access.</p>
  
  <p>All works as if the reverse proxy does not rewrite correctly URLs defined in the html source page. Have I missed something ?</p>
  
  <p>Here is my nginx configuration : </p>
  
  <pre><code>    location /jenkins {
              proxy_set_header X-Real-IP $remote_addr;
              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
              proxy_set_header Host $http_host;
              proxy_redirect false;
              proxy_pass http://jenkins:8080/;
      }
  </code></pre>
