Hi there,

I do not really understand your setup. Are you intending to say,
that you have two seperate apache instances, one serving via
mod_cache and the other one (in front) proxying requests
via mod_proxy_balancer?

Yes .

Please be very clear with your setup. Then please provide
your apache versions and your full configuration files
for both supposed apache servers.

Apache 2.2.6.

I can't provide configs, but the Listen directives are correct.

My question is whether Apache uses tcp connections for mod_cache to communicate with Apache.

Thanks. 

Quick hint: Have a look at your "Listen" directive.

regs,

Christian
