From 78f6ef08594844fde064209ab1c9617194fe3097 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Allow optional name=value options within <Proxy section line.
 Additional arguments are allowed only for 'standard' url's, meaning that the
 wildchar urls will return error like before. This allow to specify the
 worker/balancer parameters on the definition line, without the need for extra
 ProxySet options.
