mod_jk2 load balancing as a RAID 0+1 analog

[Vladyslav Kosulin <ko...@yahoo.com>]

Hi all,

Here is my configuration:

Front-ent - Apache 2.0.47/mod_jk2/ajp13.

4 instances of JBoss 3.2.1/Jetty 4.2.11 with identical ear applications are
configured as 2 pairs of fail-over clusters with <distributable/> webapp.

node1+node2 creates a first fail-over cluster.
node3+node4 creates a second fail-over cluster.

Initial http request can go to any of these 4 nodes.

After that mod_jk2 should redirect subsequent requests inside the initial 
fail-over cluster, and only if both nodes in that cluster fail, try to redirect 
to another nodes.

The problem here is that I do not know is it possible to configure mod_jk2
(workers2.properties) to redirect this way. Any ideas are highly appreciated.

Thanks,
Vlad
