Specifically, read the introduction to the "Load Balancing > Directives" section (which specifically, in RED TEXT, warns you about > setting these parameters and making sure they agree).

The only use-case I > can think of for "redirect" is when you are using the BackupManager > for session-clustering. I don't see a balancer worker defined (type lb) and configured. Some of the attributes you set belong to a balancer worker. I suggest reading http://tomcat.apache.org/connectors-doc/common_howto/loadbalancers.html The point about setting jvmRoute in your Tomcat's server.xml is very important. A good starting point for a mod_jk config is here: http://svn.apache.org/viewvc/tomcat/jk/trunk/conf/ The files are also contained in the source release of mod_jk available under https://tomcat.apache.org/download-connectors.cgi Regards, Rainer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
