[users@httpd] unable to achieve sticky session
Hi all,
I am new to httpd and using the tomcat hosts behind of httpd. ------>
(Apache2.2 and Tomcat-7)
i achieved the load balancing perfectly but unable to achieve session
replication (sticky session behavior).
Due to this i unable to login into application.
I noticed like this, At the first request it is pointing to Node-1 and at
other request to other like Node-2...etc it seems, so due not having the
session replication it is logging out and showing login page.
This is my configuration :
httpd.conf
--------------
added new content as part of httpd.conf
LoadModule jk_module modules/mod_jk.so
<IfModule jk_module>
# Path to workers.properties
JkWorkersFile E:\Apache2.2\conf\workers.properties
# Path to jk logs
JkLogFile E:/Apache2.2/logs/mod_jk.log
# Jk log level [debug/error/info]
JkLogLevel info
# Jk log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions for forwarding
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"
JkMount /ngcc/* balancer
</IfModule>
workers.properties
--------------------------
workers.tomcat_home=E:\Tomcat-A
workers.java_home=E:\Java\jdk1.7.0_21
#worker.list=worker1,worker2
worker.list=balancer
worker.worker1.port=2013
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor=1
worker.worker2.port=7080
worker.worker2.host=localhost
worker.worker2.type=ajp13
worker.worker2.lbfactor=1
worker.balancer.type=lb
worker.balancer.balance_workers=worker1,worker2
worker.balancer.method=B
# should be routed back to the same #Tomcat worker.
worker.balancer.sticky_session=True
(tested with True also)
I think there is lack in configuration it seems.... please find out and let
me know, any help is appreciated.
Thanks & regards
Nagaraju

Did you read this? Did you do the tomcat part of config setting the
jvmRoute?
