Hello,  
I’m on Rancher/server 1.6.8 and I’m trying to add custom options on haproxy.cfg for the load-balancer.  
I want to replace : `option http-server-close` by `option http-keep-alive`  
But when I add `option http-keep-alive` to the RANCHER web GUI in the section “custom haproxy.cfg” the result on the haproxy container is :  
defaults  
errorfile 400 /etc/haproxy/errors/400.http  
errorfile 403 /etc/haproxy/errors/403.http  
errorfile 408 /etc/haproxy/errors/408.http  
errorfile 500 /etc/haproxy/errors/500.http  
errorfile 502 /etc/haproxy/errors/502.http  
errorfile 503 /etc/haproxy/errors/503.http  
errorfile 504 /etc/haproxy/errors/504.http  
maxconn 4096  
mode tcp  
option forwardfor  
**option http-server-close**  
option redispatch  
retries 3  
timeout client 50000  
timeout connect 5000  
timeout server 50000  
**option http-keep-alive**

Is there a solution to replace this option and not just append it to the end of the default haproxy.cfg ?  
Thanks to you 🙂

Ok, I just tried to add this lines in the custum haproxy.cfg section, but the result is the same, It just append the lines but not replace the lines as it should.

I have this issue as well. The only way it appears to ensure my Connection: keep-alive header is sent back to the browser is if I use TCP mode instead of HTTP
