HTTPS redirection for Primo discovery system

Hello,
I am new to Haproxy…
I am trying to configure exlibris Primo accoring to these instructions:
https://knowledge.exlibrisgroup.com/Primo/Implementation_Guides/Configuration/Setting_Up_SSL_for_Local_Primo_Customers#General_DNS_and_LB_Configuration

Please, does anybody have experiences with configuring Primo https redirection, or could anybody translate these instructions to HAproxy configuration?

Thanks, elias
