Thanks Willy and thanks Thierry Fournier too (He answers some days before and
didn't get the time to test before)
It work like a charm now :-)
It's weird but no blogs speaks about this. All blogs I found do redirect to 80
on backend. Or they use 443 but there is nothing in the config explained :-(
So I really appreciate your help.
It saves me some sleep hours :-)

Yes the list is in english, but I understood your problem so I'll
put out a quick summary and will respond :-)

In short Cedric faces an issue where he gets errors 503/504 on haproxy
when passing HTTPS requests to IIS but that's OK with HTTP.
Cedric, the problem is that you are connecting to port 443 in clear
because you didnt specify "ssl" on the server lines :
backend www-backend-https
server www-1 192.168.1.2:443 check
server www-2 192.168.1.3:443 check
Just add "ssl" at the end of the line and it will work better. You'll
get a warning upon startup that you need to add "ssl-verify-none" or
to put a CA file. If haproxy and the servers are on the same local
network and you consider this network to be safe, you can easily add
that option.
Additionnally, maybe you don't even need to pass again via port 443
and you can pass everything to port 80 ? That can make a simpler
config and avoid to re-encrypt+decrypt.
Last, since you're on haproxy 1.5, if you're observing important
CPU usage when using SSL, you can enable HTTP keep-alive to the
servers by removing this line :
option http-server-close
It will use more memory by maintaining more connections though.
Regards,
Willy
