Resource based http load balancing

Hi all,

I am looking for a solution to the following issue.
Basically, we are going to be implementing a series of front end splunk search heads (basically IO intensive web servers).
And wish to automatically redirect a new connection to the search head from the pool with most available resources (ie. least load).

I would like to be able to do this via an apache based load balancing solution, as I have used it in the past. However, not sure how to go about balancing by available resources.

I have a strong knowledge in SNMP and Apache so, if there is anyway to do it, I am sure I could tackle it.

Cheers guys,
Aaron.

As I can't find anything I am now looking into modifying a sub module for the mod_proxy_loadbalancer module.

I found the sub module to work off of here:
asf - Revision 1207701: /httpd/httpd/trunk/modules/proxy/examples

Do you think I am working in the right direction?

I know alot of perl/bash but, no C... so, I am now twidling in that... :S
