Igor, Thank you for the response. (Sometimes one need to be told RTFM!) So I gather you would use the max=n parameter on each BalancerMember in your cluster. Now, what happens when each member in the cluster has reached their max and a new connection comes in? Or what happens if a request that has been pinned to a given server (through stickysession), and that server has reached its maximum number of connection? In that case, I don't want users to get a 503, but rather the request to be queued. Is this what mod_proxy does by default?
