  proxy_read_timeout   600;
  proxy_buffer_size    64k;
  proxy_buffers     16 32k;
  proxy_busy_buffers_size 64k;
  proxy_temp_file_write_size 64k;
  proxy_pass_header Set-Cookie;
  proxy_redirect     off;
  proxy_hide_header  Vary;
  proxy_set_header   Accept-Encoding '';
  proxy_ignore_headers Cache-Control Expires;
  proxy_set_header   Referer $http_referer;
  proxy_set_header   Host   $host;
  proxy_set_header   Cookie $http_cookie;
  proxy_set_header   X-Real-IP  $remote_addr;
  proxy_set_header X-Forwarded-Host $host;
