Summary: A
Product: Tomcat 5
Version: 5.5.9
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P2
Component: Native:JK
AssignedTo: tomcat-dev@jakarta.apache.org

Hi,
I don't know if this is the right place, maybe it's a bug in mod_jk, maybe in
Tomcat, or maybe there's no bug at all...
I have configured a mod_jk loadbalancer on Apache 2. I have two tomcats running
on two differents servers. I don't have activated the cluster element in
server.xml. Both tomcats are running the same webapp. In the title of every jsp
I write the name of the server so that I can check that sticky session works.
And it doesn't.
Here is my workers.properties :
----------------------------------------------------------
worker.list=loadbalancer,status
worker.node1.port=8009
worker.node1.host=noeud_1
worker.node1.type=ajp13
worker.node1.lbfactor=1
worker.node2.port=8009
worker.node2.host=noeud_2
worker.node2.type=ajp13
worker.node2.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.sticky_session=true
worker.loadbalancer.balance_workers=node1, node2
# Status worker for managing load balancer
worker.status.type=status
----------------------------------------------------------
noeud_1 and noeud_2 are the tomcat servers.
In each tomcats I've added the jvmRoute attribute :
----------------------------------------------------------
<Engine name="Catalina" defaultHost="localhost" jvmRoute="noeud_1">
------------------------------------------------------------
Of course on the noeud_2 server I wrote jvmRoute="noeud_2"...
Here is my jk.load file :
-----------------------------------------------------------
JkWorkersFile /etc/apache2/workers.properties
JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
# JkOptions indicates to send SSK KEY SIZE
#JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMount /* loadbalancer
JkMount /jkstatus status
JkShmFile /var/log/apache2/jk.shm
<Location /jkstatus/>
JkMount status
Order deny,allow
Deny from all
Allow from all
</Location>
------------------------------------------------------------
And finally here is the way I write the server name in jsps :
<title><% java.net.InetAddress local =
java.net.InetAddress.getLocalHost();out.print(local.getHostName()); %></title>
Now the test :
I open http://MY_SERVER/ in firefox :
I see "noeud_1" in the title.
I have a JSESSIONIN in HTTP Headers.
I press F5 to reload
I see "noeud_2" in the title.
I still have the same JSESSIONID...
So is it normal ? I think that the point of sticky session is to always redirect
to the same server right ? Did I forgot something in some config files ?
