Oh no, I wasn't saying to have cisco loadbalance the tomcats, I was
asking why cisco isn't load balancing your apache requests?

But yes, your answer is yes.

Subject: Re: Tomcats in two mod_jk lb-clusters simultaneously

Cause at first cisco can't balance all tomcats as precision as mod_jk
And for example if all tomcats on Server1 dies, or work soooo sloooww
(like 3mins waiting for reply, it can be in our application) but
apache still alive - cisco will dont know about it fail and users can
give a bad page with nothing =))

Anyway, reply for Q: "Its possible to include a few tomcat servers in
two different lb-clusters" is YES?
