It’s working well, even certbot running on the ,228.
I ask you a kindle opinion about configuration. It’s my first days in HAProxy and I’d like to start with right direction.
To be more precise: do I need a separate frontend and backend section? Cannot I simple listen to 80 and 443 ina single frontend and use a single backend ?
Also, I forced a 301 redirect from http to https in the server. Is it right or must I do it here at HAProxy level?
Thanks in advance
