and very basic, but it should be ready for testing. Two strategies for load balancing
are implemented: a simple round robin, and a simple weighted random. The following
is an example configuration in vcl. The weight parameter for random is optional. Default
is equal weight.

backend foo {
	set backend.host = "foo.bar.com";
	set backend.port = "http";
}

backend_round_robin rr {
	set backend.set = {
		{ "foo1.bar.com", "http" }
		{ "foo2.bar.com", "http" }
		{ "foo3.bar.com", "http" }
	};
}

backend_random rrr {
	set backend.set = {
		{ "foo1.bar.com", "http", 0.3 }
		{ "foo2.bar.com", "http", 0.6 }
		{ "foo3.bar.com", "http", 0.1 }
	};
}

sub vcl_recv {
	if {req.http.host ~ "foo"} {
		req.backend = foo;
	} elseif {req.http.host ~ "bar"} {
		req.backend = rr;
	} else {
		req.backend = rrr;
	}
}
