  /// server or client when an association between a uri and a file name
  /// needs to be made. The general operation principle is to associate a 
  /// path with a uri authority. The uri path is then concatanated to produce
  /// a new path. If the uri path is empty, it can be eventually replaced by
  /// a file name, known as the diretory index in the http terminology.
