Hi Ard/Jeroen
Many thanks for your responses.
I am actually using sticky sessions to ensure that a request from one node
is served by that node only.
<Proxy balancer://testCluster>
Order allow,deny
Allow from all
BalancerMember ajp://IP:8010 route=cmsnode01
BalancerMember ajp://IP:8011 route=cmsnode02
ProxySet lbmethod=byrequests
</Proxy>
ProxyPass / balancer://testCluster/ stickysession=JSESSIONID nofailover=off
ProxyPassReverse / balancer://testCluster/
That is the actual code from my vhost file for CMS
Actually, I have a test setup which works fine.The problem is with another
setup at a clients place.
But your post has actually urged me to verify the vhost file there which I
will do.
In the mean while please let me know if you believe there is a reason why
this is happening.
Again thanks for your responses.
