HAP 1.5.11 and SSL

[Phil Daws]

Hello all!

Long time no post but have lost some of my old notes and hitting an issue with 
SSL.  In my haproxy.conf I have:

frontend frontend-zimbra-zwc-http
        mode http
        bind 10.1.8.73:80
        redirect scheme https if !{ ssl_fc }

frontend frontend-zimbra-zwc-https
        bind 10.1.8.73:443 ssl crt /etc/haproxy/certs/mydomain.pem ciphers 
RC4:HIGH:!aNULL:!MD5
        option tcplog
        reqadd X-Forwarded-Proto:\ https
        default_backend backend-zimbra-zwc

backend backend-zimbra-zwc
        mode http
        server zwc01 10.1.8.40:443 maxconn 1000 check-ssl verify none
        server zwc02 10.1.8.41:443 maxconn 1000 check-ssl verify none backup

the HTTP connections are being re-directed to HTTPS as desired but when it hits 
the backend I see:

(NGINX) The plain HTTP request was sent to HTTPS port

If I have redirected at the frontend then why is plain HTTP being sent to the 
backend ?

Thanks, Phil
