      public BrowserPolicy(int downloadDuration, boolean entityValidation)
      It defines the management characteristics that the browser must keep in comparison with the Source it will download.
      Parameters:
      downloadDuration - is the number of seconds the browser can afford to cache the resource, without re-querying the server. Obviously this applies to the identification of the resource which therefore includes the recovery coordinates (windowmanager,finestra, ecc).
      entityValidation - allows to activate the validation of entities through ETag, thanks to which, after the duration of the cache, the server may respond 307, avoiding the download of the resource, as it hasn't changed. Prerequisite to activate this mechanism is that the Source implements the getEntityTag
