Hi We have a cluster of Linux (RedHat) machines each housing an apache, 4 tomcat instances and 4 other jvms that run our custom servers. Each tomcat has a corresponding custom server that it delegates requests to. In other words, there is one to one correspondence between a tomcat instance and a custom server instance. Problem is that when a custom server crashes and its tomcat is still accepting, mod_jk does not mark it down. Consequently users continue to be directed to that tomcat even though they are experiencing errors. In mod_jk, we have defined a load balancing worker that fronts the 4 tomcat workers. So questions are:
1. On what basis does mod_jk mark a tomcat worker down? Is it http return codes? 2. Some load balancers allow scraping of the http body to see if there is an error in addition to relying on http codes. Is that possible in mod_jk? Is it configurable? 3. Is it possible to stop|start a mod_jk worker via an http call? Or some other programmable way? Any ideas on how to solve this problem?
