// there is an existing cache entry, this class only writes supplied data back
// if there is a cache mismatch.

// Note that writes done by this class cannot be "short" - ie, if they succeed,
// they always write all the supplied data back. Therefore completions are
// signalled with net::Error without a count of bytes written.
//
// This class's behavior is modelled as a state machine; see the DoLoop function
// for comments about this.
