X-Forwarded-For not working

Help!
6

Sorry, so now I have those 3 lines in the frontend:

  option forwardfor
  capture request header X-Forwarded-For len 15
  log-format %[capture.req.hdr(0)]:%cp\ [%t]\ %f\ %b/%s\ %Tq/%Tw/%Tc/%Tr/%Tt\ %ST\ %B\ %CC\ %CS\ %tsc\ %ac/%fc/%bc/%sc/%rc\ %sq/%bq\ {%hrl}\ {%hsl}\ %{+Q}r

And this is the HAProxy log I get:

haproxy[76963]: 10.11.109.4:35474 [29/Mar/2019:15:51:24.921] www_el_ssl~ archive_ssl_back/r4 0/0/0/2/2 200 428 - - ---- 7/6/0/1/0 0/0 {} "GET /VAADIN/themes/base/shadow/img/bottom-right.png HTTP/1.1"

So I am asuming that inside {} I should see the headers being logged, right? including x-forwarded-for

Logging the headers is just for debugging purpose, I don’t actually need it, I would only need the X-Forwarded-For to be passed to the backend.
So users hit port 80 on HAProxy, then I redirect to 443, then it goes to a backend that could be either SSL or non SSL.

Thanks.
