I see a lot of typos "istance" instead of "instance". Are you sure you
have everything spelled correctly in your configuration?
Yes, "instances" reported here were just for an example. "istance" were
a missplelled...
So my Apache configuration for stickysession is as follow:
----- ProxyPass /myApp/ balancer://balance-this/myApp/
<Proxy balancer://balance-this> BalancerMember ajp://node01:10505
route=instance01_node01 BalancerMember ajp://node01:10505
route=instance02_node01 BalancerMember ajp://node02:10505
route=instance01_node02 BalancerMember ajp://node02:10505
route=instance02_node02
ProxySet stickysession=JSESSIONID nofailover=On</Proxy> -----
And this works fine!
Good.
BUT, if I have jvmroute parameter configured with the same value
for all my tomcat instance (e.g. jvmroute="myRoute") and so apache
configured as follow
[...]
it still works!!! I do not lose my session! Why??? Have to jvmroute
be unique or not???
That's probably because you are only being directed to a single Tomcat
backend. mod_proxy_ajp probably picks the first worker that matches
the jvmRoute and it doesn't care that they are all the same. If you
run a load test against the cluster, I suspect that you'll end up with
100% of the load going to a single Tomcat backend.
Exactly, I ran more load test and all end up on the first tomcat
instance....
Thanks for the reply.
Francesco.
