I just tried it with httpd 2.2.8 and it works for me. Although there
seeems to be no fit in the httpd changelog, 2.2.3 is a little early in
the 2.2.x release cycle and the balancer and balancer manager were new
in 2.2.x, so if nothing else helps, upgrading to a more recent 2.2.x
(like 2.2.8 or 2.2.9 expected in a few weeks) would be worth trying. I
think I remember having it used with 2.2.6, but I didn't try it with
2.2.3 or earlier.

Others?

Apart from that: the httpd users list might be a better place to ask,
because this seems not to be related to some difficult AJP13 stuff
instead it seems to be a more general httpd mod_proxy_* issue.

Regards und Grüße nach Wien
