INTERNET SERVER ACCESS CONTROL AND MONITORING SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide a method for controling and monitoring access to a network server.

SOLUTION: In the hypertext environment, a client observes a document transmitted by a content server with a standard program known as the browser. Each hypertext document or page contains links to other hypertext pages which the user may select to traverse. When the user selects a link that is directed to an access-controlled file, the server subjects the request to a secondary server which determines whether the client has an authorization or valid use requirement. Upon such a verification, the user is provided with a session identification which allows the user to access to the requested file as well as any other files within the present protection domain.
