System, method and apparatus for use in monitoring or controlling internet access |
摘要 |
An apparatus method and system are described for categorizing Uniform Resource Locators (URLs) when accessing the Internet 20 from a client 12. A request message 500 is generated to request categorization of a specified URL, and a category is provided in a reply message 600. The specified URL and the category are added to a category cache. In a second or subsequent instance of a URL request referring to the specified URL, the category is determined from the category cache. This reduces communication traffic in a network such as the Internet 20.
