Apache2/Tomcat55/mod_jk and Sticky Sessions

[Dave Morrow <da...@autodata.net>]

Hi all.  I am attempting to setup a loadbalanced set of Tomcat5.5 servers behind an Apache2 server using mod_jk.  The application developers have told me that the app will require sticky sessions.  I have it all configured and working with the exception of the sticky sessions.  I think my workers.properties is correct so there must be something I am missing.  For testing, I created a JSP in the ROOT application of each of the Tomcat servers which simply displays the server name and SessionID.  The loadbalancing is working, but instead of maintaining a session, it's flip-flopping between servers and thus changing session ID's.

My workers.properties contains (note the localhost is in the opposite place on the other server);

worker.list= qatomcat1, qatomcat2, loadbalancer #
worker.qatomcat1.port=8009
worker.qatomcat1.host=qahost1
worker.qatomcat1.type=ajp13
worker.qatomcat1.lbfactor=100
worker.qatomcat1.local=0
#
worker.qatomcat2.port=8009
worker.qatomcat2.host=localhost
worker.qatomcat2.type=ajp13
worker.qatomcat2.lbfactor=100
worker.qatomcat2.local=1

Dave,

Try a Google search for: "Apache httpd sticky sessions".
One result that looks particularly useful: http://raibledesigns.com/tomcat/
