HaProxy Load Balancer and Nginx Basic Auth

Question

I have a nginx server with basic auth

 location / {
      root   /var/www/mywebsite.com;
      index  index.html index.htm;
      auth_basic "Restricted";                                #For Basic Auth
      auth_basic_user_file /etc/nginx/.htpasswd;  #For Basic Auth
  }

The server is behind an HAProxy Load Balancer. is there a way that I can have the load balancer send the username and password to nginx to authenticate?

How should the configuration be if the authentication is for Nginx not HA? Or is it impossible to do it? — jxStackOverflow

I figured it out, two step answer.

Step 1 Base64 encode the username and password. Lets say the user is johndoe and the password is abc123.

$bash: echo -n johndoe:abc123 | openssl enc -a
Output: am9obmRvZTphYmMxMjM=

Step 2 is to add it to the backend of your HAProxy config

backend application-backend
    balance     roundrobin
    log             global
    option http-server-close  
    option forwardfor
    reqadd Authorization:\ Basic\ am9obmRvZTphYmMxMjM=
