Hi,
I'm trying to setup mod_proxy_balancer on a server and I couldn't get the "Sticky Session" working , this is my configuration:
----------------------------------------------------------------------------------------------------------------------------------
ProxyPass / balancer://appcluster/ lbmethod=byrequests stickysession=SESSIONID
ProxyPassReverse / balancer://appcluster/
<Proxy balancer://appcluster>
BalancerMember http://10.1.1.100:8080
BalancerMember http://10.1.1.101:8080
BalancerMember http://10.1.1.102:8080
BalancerMember http://10.1.1.103:8080
BalancerMember http://10.1.1.104:8080
</Proxy>
----------------------------------------------------------------------------------------------------------------------------------
According to the logs, apache gets the session ID, but every two
requests it redirects me to a different server. As I know, the "Sticky
session" is used to keep the sessions going to the same server, but for
me is not working. Below it is the part of the logs where you can see
that it is sending my requests to differents servers.
The backend servers are running tomcat.
Please, I would need to know if there is something wrong or missing on
my configuration and if you need something else for the httpd.conf
file, let me know.
Thanks,
Charly
