PROBLEM TO BE SOLVED: To carry out a more selective access to resources in a network protected by a firewall. SOLUTION: In a communications network accessible using an HTTP, a reverse proxy server is coupled to an intranet and also coupled to a browser enabled client. The requests for access to resources inside the intranet are made through the reverse proxy server. Access to the requested resource is provided to the client by means of a capability-enabled URI having a character string that is produced by encoding an identification number and a random number. The character string, the identification number and the random number are associated with database record accessed by the reverse proxy server to determine whether access is to be provided to the client, and what conditions to apply to the access when the capability-enabled URI is invoked.
