Hi Lance. Please keep the list in the loop as there are several other persons which can also help, thank you.

Thanks! docx with embedded Images is not a very secure nor a common format on this list, due to this fact let me copy the content of the docx here and comment it inline and answer below. > Haproxy.cfg: > global >log /dev/log local0 >log /dev/log local1 notice >chroot /var/lib/haproxy >stats timeout 30s >user haproxy >group haproxy >daemon >maxconn 15000 > > defaults >log global >mode http >option httplog >option dontlognull >timeout connect 5000 >timeout client 5 >timeout server 5 > > frontend myserver.net >bind *:443 >mode tcp Okay here is the problem. As the haproxy is only used for tcp proxying not for http you will not be able to make what you want. https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4-mode >maxconn 15000 >default_backend hac_cluster > > backend hac_cluster >mode tcp >balance leastconn >server myserver 192.1.1.1:443 check maxconn 5000 >server myserver 192.1.1.2:443 check maxconn 5000 > >listen statistics >bind *:80 I would not recommend to put statistics on port 80, but that's only my opinion. >mode http >stats enable >stats hide-version >stats refresh 30s >stats show-node >stats auth myserver:password >stats admin if TRUE >stats uri /lbstats > > > haproxy -vv >> ## excerpt from image > Version 1.7.8 > No compression libs, openssl, pcre nor lua support On which platform is this haproxy running? Is haproxy installed from the package management or was it build from sources? To be able to do what you want you will need to do the following steps. * Install haproxy with openssl support * get the certificates from the backend server and add it to the haproxy https://www.haproxy.com/blog/how-to-get-ssl-with-haproxy-getting-rid-of-stunnel-stud-nginx-or-pound/ - Pay attention that you copy teh certificates into the chroot dir >chroot /var/lib/haproxy * create a frontend acl for the path `acl my_site path_beg -i /site` * create a use_backend line `use_backend my_site if my_site` * create a backend with the name `my_site` with the server line like `server myserver myserver.net: ...` As I mentioned before it's not a easy task to dig into this topic, therefore I strongly recommend to give you and your programmer some time to understand how load balancing on level 6(TLS/SSL) + 7(http) works. Here are some links which could help to get a better picture of HAProxy and LB in general. http://www.haproxy.org/download/1.7/doc/intro.txt https://www.haproxy.com/blog/the-four-essential-sections-of-an-haproxy-configuration/ https://www.haproxy.com/blog/introduction-to-haproxy-acls/ In any case please post some logs, configs or anything directly in the mail body so that the persons which reads this list via a console are able to follow it without to open a word document. We are glad to help as long as we can read the mails ;-) Very best regards Aleks > -----Original Message- > From: Aleksandar Lazic > Sent: Thursday, December 20, 2018 4:21 PM > To: Lance Melancon > Cc: haproxy@formilux.org > Subject: Re: HA Proxy Load Balancer > > > > CAUTION: This email originated from outside Cypress-Fairbanks ISD.
