Groups

Instances can be assigned to one or more groups.

{
	"instances": [
		{
			"Name": "instance-1",
			"Group": [ "foo", "bar ]
		},
		{
			"Name": "instance-2",
			"Group": [ "foo" ]
		},
		{
			"Name": "instance-3",
			"Group": "baz"
		}
	]
}

If the proxyByName (argument -n) configuration property is set to "group" requests can be routed to a group of instances using the username field in the proxy URL. For example, using http://foo:@localhost:9080 as the proxy URL will send requests to "instance-1" and "instance-2" rotating them in a round-robin fashion.
