Hi Fred,
Thanks for the reply.
I have two peers synchronising (we use keepalived over the two to control which
is live).
HAProxy config:
peers lb_replication
peer server1 10.128.176.141:1024
peer server2 10.128.176.142:1024
backend sourceaddr
stick-table type ip size 10240k expire 30m peers lb_replication
frontend ft_web_ssl
bind 0.0.0.0:443 name https ssl crt /etc/haproxy/certs/main.pem
mode http
option httplog
acl is_from_outside src 192.168.110.0/24
acl is_empty_path path /
acl is_webmail hdr(host) -i webmail
acl is_webmail_fqdn hdr(host) -i webmail.domain
redirect location /owa/ code 302 if is_webmail is_empty_path !
is_from_outside
redirect location /owa/ code 302 if is_webmail_fqdn is_empty_path !
is_from_outside
default_backend bk_web_ssl
backend bk_web_ssl
mode http
option httplog
cookie SERVERID insert nocache indirect
stick on src table sourceaddr
server server1 10.128.176.150:443 check ssl
server server2 10.51.0.150:443 check ssl backup
It's fine for new connections - it records the correct server1/server2
information. It's hard to demonstrate, but I can see when I use haproxyctl to
clear an entry :
Haproxyctl clear table sourceaddr key <key>
.. it doesn't clear the secondary node entry. When that entry for the client
re-presents the expiry time on the secondary updates but the entry never clears.
I can't really include pictures on these emails, but the tables are kind of
standard:
e.g.
0x7fa8b247a4f4: key=217.40.203.34 use=0 exp=1574957 server_id=1
Thanks
Andy

Please give us more information about your configuration. If possible,
also provide us with the information of stick-table entries concerned
with this issue (see "show table" CLI command).
Do not forget to obfuscate the critical data.
Regards,
Fred.
