Web pages did not sync with Mod_jk loadbalancer configured with Apache and Jboss in Linux server

Hi,

I have a website that is configured on Jboss on Two Linux instances. Apache Mod_jk is working as a load balance with jboss.

We have a problem with the login process.
•      I went to Firefox and clicked Sign In Here and log in with my credentials at 7:27:20.
•      35 seconds later (7:27:55), the login process appears to have completed; however, the site still says Sign In Here:
o
•      So I clicked refresh pages and then Account Administration and the site still said Sign In Here.
•      Thinking that the site did not log me in I tried again (47 seconds).
•      The site next took me to the Account Administration page and now said Welcome test user:
o
•      I logged out and the site properly said Sign In Here. Then I clicked For refresh page and the site said “Welcome test user” but I logged out so why does this happen?

I tried another browser, Chrome:
•      I signed in and it took 38 seconds. This time it properly says Welcome test user
•      I went to For refresh page and was still logged in so I logged out again and the site properly says Sign In Here.
•      Then I clicked Sign In Here and the login page says Welcome test user and has the blank fields for login. This should be impossible:

•      I tried logging in as another user and the site says incorrectly says Sign In Here. I clicked For refresh pages and it said Welcome [with the user’s name], making it look like I am logged in.
•      Then I clicked Account Administration and I am brought to the Sign In page as if I am not logged in.
•      Now I try logging in repeatedly and it keeps asking me to Sign In.
The login is definitely not working right. It says Welcome [Your Name] when you are logged out and Sign In here when you are logged in.

What i did to verify jboss functionality is:

i stopped jboss service from instance A. it works perfectly.

i started jboss service from instance A and stopped jboss service from instance B. it works perfectly.

So i believe Mod_jk load balancer is misbehaving.

Please suggest.

I have implemented loadbalance through Mod_jk

Here is worker.properties configuration.

# Define list of workers that will be used
# for mapping requests
# The configuration directives are valid
# for the mod_jk version 1.2.18 and later
#worker.list=loadbalancer,status
#worker.list=node2
worker.list=loadbalancer,status,node2,node1
######START Current Relaese Nodes##########

# Define Node2 Web Live
worker.node2.port=8010
worker.node2.host=192.168.90.6
worker.node2.type=ajp13
worker.node2.lbfactor=1
#worker.node1.prepost_timeout=10000 #Not required if using ping_mode=A
#worker.node1.connect_timeout=10000 #Not required if using ping_mode=A
#worker.node2.ping_mode=A #As of mod_jk 1.2.27

# Load-balancing behaviour
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=node2,node1
#worker.loadbalancer.sticky_session=1

# Status worker for managing load balancer
worker.status.type=status

Here is the configuration of apache for the website

:

<VirtualHost 192.168.90.6:80>
ServerName www.testprotocols.com
ServerAlias testprotocols.com
CustomLog logs/access_log combined

JkMount /cdp/view/AbouttestProtocolsMobileWebsite.html node2
JkMount /* loadbalancer

#ProxyRequests Off
# ProxyPreserveHost On
#RewriteEngine On

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REMOTE_ADDR} (.*)
RewriteRule .* - [E=R_A:%1]
RequestHeader add TEST_SRC_ADDR %{R_A}e
RewriteCond %{HTTP_HOST} !^www\.testprotocols\.com [NC]
RewriteRule ^(.*)$ http://www.testprotocols.com$1 [L,R=301]

</IfModule>

Here is Mod-jk Configuration details

:

# Load mod_jk module
# Specify the filename of the mod_jk lib
LoadModule jk_module modules/mod_jk.so

# Where to find workers.properties
JkWorkersFile conf/workers.properties
#JkWorkersFile conf/workers1.properties
# Where to put jk logs
JkLogFile logs/mod_jk.log

# Set the jk log level [debug/error/info]
JkLogLevel info

# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

# JkOptions indicates to send SSK KEY SIZE
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat
JkRequestLogFormat "%w %V %T"

JkShmFile logs/jk.shm
# Add jkstatus for managing runtime data
<Location /jkstatus/>
JkMount status
</Location>

</VirtualHost>

Please suggest, where i am missing the point.

Thanks for your help.
