Method of processing requests, and a proxy server

A non-transitory computer-readable data medium storing a computer program having instructions, which when executed by a processor of a proxy server configure the proxy server to perform a method of processing requests, the proxy server being a server of resolution of domain names of a first communications network, said first communications network being accessible by a user terminal via a communications tunnel set up over a second communications network, said processing comprising, on receiving a domain name resolution request coming from the terminal and sent via the communications tunnel:

• an obtaining act of obtaining an identifier of the user from information contained in a field of the request;
• a determination act of using said identifier of the user to determine whether the user is or is not authorized to access said domain name;
• if the user is authorized to access the domain name, a send act of sending an IP address to the terminal via the communications tunnel, the IP address corresponding to the domain name and being accessible to the terminal via said second communications network;
• else, a rejection act of rejecting the request from the terminal.

A proxy server of domain name resolution forming part of a first communications network accessible by a user terminal via a communications tunnel set up over a second communications network, said proxy server comprising:

• a processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon which when executed by the processor configure the proxy server to perform the following acts on receiving a domain name resolution request coming from the terminal and sent via the communications tunnel:
• obtaining an identifier of the user from information contained in a field of the request;
• using said identifier of the user to determine whether the user is or is not authorized to access said domain name;
• if the user is authorized to access the domain name, sending an IP address to the terminal via the communications tunnel, the IP address corresponding to the domain name and being accessible to the terminal via said second communications network;
• and
• else rejecting the request from the terminal.

A communications system comprising:

• a user terminal configured to set up a communications tunnel with a first communications network over a second communications network;
• and
• a proxy server of resolution of domain names of the first communications network accessible by the user terminal via the communications tunnel set up over the second communications network, said proxy server comprising:
• a processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon which when executed by the processor configure the proxy server to perform the following acts on receiving a domain name resolution request coming from the terminal and sent via the communications tunnel:
• obtaining an identifier of the user from information contained in a field of the request;
• using said identifier of the user to determine whether the user is or is not authorized to access said domain name;
• if the user is authorized to access the domain name, sending an IP address to the terminal via the communications tunnel, the IP address corresponding to the domain name and being accessible to the terminal via said second communications network;
• and
• else rejecting the request from the terminal;
• said terminal also being configured:
• to send to the proxy server, via the communications tunnel, all of its domain name resolution requests;
• and
• on receiving the IP address from the proxy server in response to the domain name resolution request, the IP address corresponding to said domain name, to transmit at least one data stream to said IP address without passing via said communications tunnel.
