Abstract

A method of downloading resources to a client ( ) from a content server ( ) over a data network. A resource request message is sent from the client ( ) and is intercepted at a proxy ( ) located in the data network between the client ( ) and the content server ( ). A header request is sent from the proxy ( ) to the content server ( ), requesting the content server ( ) to transmit a header, associated with the requested resource, to the proxy ( ). The header is received at the proxy ( ) which determines whether or not the header contains billing and/or access restrictions. In the event that the header does contain billing and/or access restrictions, the client's right to receive the requested resource is authenticated and, providing the client is authenticated, the resource request message is delivered from the proxy ( ) to the content server ( ) and subsequently the resource is downloaded from the content server ( ) to the client ( ).
