I'm not shure if mod_jk will use the second worker if the first worker doesn't work any longer if you have a lbfactor of 0 for the second worker. If this isn't the case apache should answer with an error code. If you have a http load balancer it should recognise this. (As you said that the balancer even supports sticky sessions I would expect this) Otherwise mod_jk should rout all request to the second worker. (If mod_jk doesn't use the second worker with lbfactor=0 you may try to use 1 instead and something like 100 for the first worker) > If I have 2 Apaches and 3 Tomcats then with out loadbalancing > in mod_jk a1 goes to t1 a2 to t2 and t3 gets its requests > from where?

I was thinking in terms of 3 apaches and 3 tomcat, not in having a higher number of tomcats than apaches. In this scenario you would need load balancing in mod_jk (which, according to Bill Barker, isn't perfect in the current state, as it doesn't distribute the load even across the workers, due to some missing communication between the workers) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
