CONSTITUTION: Filtering resources are obtained and filtering is started(S22). Module gathering, file loading, and a file request are performed(S23). It is determined whether file gathering is found or not(S25). If file gathering is not found, file gathering is performed and a file is provided. If file providing is terminated, filtering is terminated and the filtering resource is released(S30). |
