Apache Load Balancer Manager query

Hi,

I have managed to get Apache working with two mongrel instances using
proxy_balancer … at least I think I have.

When I look at the Load Balancer Manager page it just says:
<<<<<<<<<<<<<<<
Load Balancer Manager for localhost

Server Version: Apache/2.2.4 (Win32)
Server Built: Jan 9 2007 23:17:20
<<<<<<<<<<<<<<<

The rails app works fine but how do I check that the that both
instances are being used as they should be?

Cheers
Giorgio
