Load balancing and Sticky sessions
Hello,
I have Apache and 2 tomcats running on 2 separate servers which are in a
cluster. I am running Tomcat 4.0(using ajp13) via mod_jk. I am also using
load balancing.I am losing my session variables when there is a switch
between the 2 tomcats. Any help is greatly appreciated.
thanks in advance,
Kavitha

Hi Ben,
session replication is working for Tomcat 5, and I have back ported a
version to tomcat 4.1.x

Unless you have session replication going on between the two Tomcats (or
are running Tomcat 5...doubtful since it is in its infant stages), you
will always lose your session if you get sent from one Tomcat to
another.

Hi Kavita,
what clustering library are you using.
There are several options that we can offer you to do.
1. Try the clustering that is going to ship with Tomcat 4,
http://www.filip.net/tomcat-clustering.html
2. Take out Apache out of the equation to make sure your clustering is
working clustering.
At the end of the page that I mentioned above, there is a Java loadbalancer
for testing (do not use this in production :) that you can use to test out
session replication.
Once you've done that, feel free to send your logs so that we can help you
determine the rest of your problems
Filip
