A system and method of controlling communication. An appliance is provided with a program suitable for issuing a DNS request and a control program enabling the DNS request to be intercepted. The control program includes communications elements for communicating with a DNS server to which the DNS request is transmitted, and for communicating with another server for authorization. An authorization request, distinct from the DNS request, including an identifier of the user of the appliance and the domain name, is transmitted to the DNS server. The authorization server returns to the DNS server a response established as a function of the identifier of the user of the appliance and as a function of the domain name contained in the authorization request. The communications elements for communicating with the issuing program transmit to the issuing program an IP address defined as a function of the response from the authorization server. |
