It is possible to override this setting when making direct calls to ad(), as described in the documentation.  Using the JavaScript display method allows you to display random ads and track views even on cached pages.  Using the Raw method does not work well together with Drupal\'s page cache enabled as the advertisements will not change until the page cache is updated, and statistics will not be incremented each time an advertisement is displayed.');
