Apache Clusters

[DualFusion]

Hi,

I have 5 servers:
1) Loadbalancer/Root
2) Apache node
3) Apache node
4) NFS
5) Mail

And I have been trying to get server1 to transfer data to each Apache node depending on there file type, not just what folder they are in. For example I may want to have PHP go to Apache node1 and Ruby into Apache node2

I have looked at the two tutorials with no success:
http://www.howtoforge.com/set-up-a-loadbalanced-ha-apache-cluster-ubuntu8.04
http://www.howtoforge.com/reduce-apache-load-with-lighttpd-debian-etch

Thanks,
Kevin.

Forgot to note that I also want server1 to be DNS. So I basically want a solution that would let me install DNS and would also load-balance between my 2 apache nodes, but will make sure all PHP files go to node1 while all Ruby goes to node2.

Thanks,
Kevin.

Can't someone help? Please? This is really important and can't continue without this step. I have been stuck with this problem for a couple days now. Any help is much appreciated.

Thanks,
Kevin.
