Well we could provide the Tomcat load by many ways but I rather like
keep them compatible with AJP13 :
- Add a new message from jk to tomcat, like the CPING/CPONG, to get
the expect load on tomcat. jk could decide to send this information
packet each X requests.
- Add a custom header in reply

IMO those kind
+1, that's what the original goal of AJP14, extending protocol from
just requests forwarding to service/system messaging.
BTW, we should disable it by default on jk, to avoid problem with old
tomcats release :)

Hi,
We need to use Apache to load balance a set of Tomcat servers.
However, we need to use a custom load-balancing algorithm, based on the
usage of those servers.
Is this possible with mod_jk? Would it be easy to extend it? Any other
suggestions?
Yes, it's possible, but

Thanks very much for the reply.
Ok, how is it possible? What would we need to extend / where would we plug

But it is. You need to write your own mod_proxy_balancer.

Hi Mladen,
That sounds feasible...but I have no idea how to do that!!
Would you mind pointing me in the right direction?
- how do we create custom headers? Where?
Inside Tomcat.
Not sure where, but some sort of filter should help.
Take a look at filter documentation if

Thanks! It seems a little daunting!
So, exploring other possibilities before I undertake it...
Is there any way to just make a call and update the load factors on the
fly?
Not right now. The mod_jk 1.2.9 will have something Apache2.1
