Hi Aaron,
Here is my haproxy configure
frontend kylin-web
bind 192.168.1.120:7077
acl url_static path_beg -i /kylin
stats enable
stats uri /haproxy?stats
stats realm Strictly\ Private
default_backend app
#---------------------------------------------------------------------
backend app
balance roundrobin
server hdp01.example.local 192.168.1.100:7070 check
server hdp02.example.local 192.168.1.101:7070 check
HAproxy:
When I login to LB 192.168.1.120:7077/kylin and do query. I can see request
loadbalance to all backend server( no need re-authentication). First request to
HDP01, second request to HDP02 and third request to HDP01……
But when I use RESTful API following this docs
http://kylin.apache.org/docs16/howto/howto_use_restapi.html
I using cookie to save authentication, that mean client do not need
re-authentication for each request sent. So problem happen here,
Example when client login to LB, it create JSESSIONID and save to cookie.
JSESSIONID point to only HDP01 server so all subsequent request go to this
server. When client authentication again, JSESSIONID point to only HDP02 server
and all subsequent request go to this server.
So what I want here:
Client login to LB, request sent will be forward balance to HDP01 and HDP02
server, client no need re-authentication.
Thanks!

Hi
I use HAproxy to loadblance my backend servers.
But I have problem when I using cookie.
When a cookie is present, the same backend server is used until it dies. So it
make overload on this server while other servers free.
If not using cookie, Each client need pass authentication to request data from
backend servers. It work ok but take long time to finish many requests from
client.
So any solution for my case, I want use Haproxy to load balance session with
client and backend server. When client send request, it will forward balance to
backend servers( not only one server when use cookie). And client do not need
re-authentication when send subsequent request
Thanks!
Best Regards,
