A method of providing rating information in respect of Uniform Resource Identifiers to a client terminal. The method includes identifying a Uniform Resource Identifier at the client terminal, sending a first query to a rating server over an IP network, the query including as a query string a first component of the identified Uniform Resource Identifier or a derivative of that first component, and receiving the first query at the rating server and determining whether or not a rating exists for the query string. A response is sent by the server to the client terminal, the response including a determined rating, or an indication that no rating exists. The response is received at the client terminal and, if a rating included in the response so indicates or if the response otherwise so indicates, then a further query is sent to the rating server, the further query including as a query string said first component and a second component of the identified Uniform Resource Identifier, or a derivative of the first and second components. The steps of receiving the first query at the rating server, sending a response, and receiving the response at the client terminal, are repeated one or more times as required, adding for each iteration a further component to the query string. |
