You need define multiple backends. No need for separate instances.

backend bkcontentcom {
     .host = "10.100.1.1";
     .port = "8080";
}

...

backend bkcacheorg {
     .host = "10.100.1.2";
     .port = "8080";
}

And in the begining of vcl_recv()

if (req.http.host ~ "^(www\.)?content\.com$") {
	set req.backend = bkcontentcom;
} else {
	// for cache.org
	set req.backend = bkcacheorg;
}



And of course your backends need to provide correct Cache-Control
headers (ie. max-age or s-max-age).
