apache mod_jk send request to all cluster nodes

问题:

I have a distrubuted cluster system. I have set up apache server and set loadbalancing (mod_jk) conditions. And also sticky session is true mode. Is it possible that could I send some special requests (after request header control) to all tomcat cluster nodes ? Is there any rule or method ?

There is no need to send back to clients, all nodes be informed from special url is enough. I have configured uriworkermap.properties, there are 3 status(active, disabled, stopped) for loadbalancer nodes. Is there any solution by configuring uriworkermap.properties or workers.properties?

For solution of this problem, suggesting alternatives of mod_jk ?
