Another example where a virtual host component comes in handy is when you want to
provide per-virtual-host level access logs (presuming you are running stand alone and
not attached to Apache).  This would be really easy to implement as a virtual host level
Interceptor, where the postInvoke() method can look at the response that was created to
prepare its log entry.
