 // A UrlInfo object is used to store prediction related information about a host
 // port and scheme triplet.  When performing DNS pre-resolution of the host/port
 // pair, its state is monitored as it is resolved.
 // It includes progress, from placement in the Predictor's queue, to resolution
 // by the DNS service as either FOUND or NO_SUCH_NAME.  Each instance may also
 // hold records of previous resolution times, which might later be shown to be
 // savings relative to resolution time during a navigation.
