G'day,
Ya. You are right. I think tomcatId is just something tomcat uses to
internally to keep track of the workers. It could be anything such as
tomcatId=worker1:8009
but you really define the host and the port in the [channel...] section as
you mention. You could have multiple workers pointed at the same host on
the same port. The only way to tell them appart is by the tomcatId. (I
think).
There is a little bit of difference between the configs if you run tomcat
and apache on the same box or if they are two seperate boxes. I think
that is the most confusing part/lack of docs.
