I have also add ant task to automate the mod_jk 1.2.15 status worker
operations.
The tomcat-jkstatus-ant.jar exits inside tomcat 5.5.14 release.
Here my example: Please, change the worker names

I would like to remove a Tomcat node from the cluster without first
shutting it down to allow any requests in progess to complete. Is it
possible to instruct Apache to stop routing requests to the node and
failover another node yet allow all requests in progress to complete.
You can do this via the status worker. It has a web interface.
I tried updating the workers.properties file and setting
disabled=True
but it did not have any effect. It seems Apache does not re-read the
file after a modification.
Apache doesn't re-read its configuration. On a Unix-like operating
system
Apache can reload the configuration, however.
Kind regards,
Wolfgang
