           Summary: Tomcat Connectors 1.2.19 sticky sessions not sticky
           Product: Tomcat 5
           Version: Unknown
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Connector:AJP
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: simon.lorenz@fresca.co.uk


Since upgrading from Tomcat Connectors 1.2.15 to 1.2.19 we find that session
affinity between apache and a tomcat/jboss instance is lossed. It appears that
the connector will quite frequently direct traffic to the first worker in a LB
pool rather than the one with the correct JVMRoute for the session.

Rolling back to 1.2.15 has resolved this issue. No other conf changes were made
as part of this upgrade.

Sorry, I misspelled jvm with jmv!

Now it works fine.

I have the same problem with JK 1.2.20.

I have this strange behaviors I found in mod_jk.log

Stick session is true and my session is on jvm_web1 route, because I found this:

> service::jk_lb_worker.c (840): service sticky_session=1
id='0D8CB99EBC3F747DA5B66183C67C8BF6.jmv_web1' 


>get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial
sessionid 0D8CB99EBC3F747DA5B66183C67C8BF6.jmv_web1
>get_most_suitable_worker::jk_lb_worker.c (741): searching worker for session
route jmv_web1 
>get_most_suitable_worker::jk_lb_worker.c (785): found best worker jvm_web2
(jvm_web2) using  method 'Request'

But it found jvm_web2 as best worker!
