The embedded URL server 40 separately performs processing for a request received from the URL filtering device 20 at normal time and periodical batch processing which is a preparation to perform the processing with high speed. Usually, a request number is counted, a document of a URL with a large count is analyzed by the batch processing, and an embedded URL is preliminarily stored in an embedded URL database 43 so as to be readable.
