HAProxy implementation Case Study This tutorial covers HAProxy Deployment on Firewall and SELinux enabled Centos7 systems. First of all lets get an overall idea about my situation. I've bought a domain call mycompany.com so all of my hosted sites should be followed by this main domain. As an example, if someone look for london.mycompany.com he should reach to London server, if someone look for chicago.mycompany.com he should reach to Chicago server So, I've created a Cloudflare account and point mycompany.com to our public IP address and created two CNAME entries from Cloudflare by adding London and Chicago. From the Cloudflare all the request to mycompany.com will forward to our public address and HAProxy may read those requests and Process them and forward them accordingly between two IIS servers. Note that all HTTPs connection should terminated at HAProxy. Please see my post HTTP
