如何在openshift golang应用程序上将HTTP重定向到https?

我有一个可扩展的golang应用程序在openshift免费层上运行.它使用位于 https://github.com/zolamk/openshift-go ，我想将http重定向到https，我尝试按照

I have a scaled golang application running on the openshift free tier. It uses a custom cartidge located at https://github.com/zolamk/openshift-go and i want to redirect http to https, i tried following the guide at Technical FAQs by using .htaccess file but that didn't work, maybe because haproxy is used as a load balancer, so my question is how can i redirect HTTP traffic to HTTPS without touching my application code if possible? maybe by changing the haproxy.cfg file, here is what my `haproxy.cfg file looks like

defaults
    mode                    http
    log                     global
    option                  httplog
    option                  dontlognull
    option http-server-close
    #option forwardfor       except 127.0.0.0/8
    option                  redispatch

    timeout server          1m
    timeout http-keep-alive 10s
    timeout check           10s
    maxconn                 128

listen stats 127.9.80.3:8080
    mode http
    stats enable
    stats uri /

listen express 127.9.80.2:8080
    cookie GEAR insert indirect nocache
    option httpchk GET /
    http-check expect rstatus 2..|3..|401
