The web filtering system includes a first database and a first computer in the server side, and a second database and a second computer in the client side. The first database stores URLs of websites and categories corresponding to the URLs, while the second database stores periodically delivered records constituting part of all records stored in the first database. When an access request to a website occurs, the second computer first tries to determine a category corresponding to a URL of the website by using the second database. Then, when the category is not determined here, the first computer executes determination by using the first database. Thus, the web filtering system minimizes the communication amount between the server side and the client side and shortens the response time required for the control of access requests to websites."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Web filtering system","description":"A web filtering system efficiently controls whether to permit access to a website.
