to authenticate the user by the radius server and to authorize the access after the access has been authorized the radius server 32 sends a response access accept to the radius client 18 or 20 the radius client 18 or 20 then sends an accounting start to start the session and an accounting stop at the end of the session thus the radius protocol allows triggering a radius client agent rca 36 responsible to gather and send information related to the user and the connection such information is then sent by the rca 36 to a provisioning proxy agent ppa 38 which is in a preferred embodiment incorporated in the proxy server 22 the ppa 38 configures the proxy server 22 to add the information in the user 39 s request the proxy can use this information to build a cookie or to add an http header in the http requests to the destination of the application it must be noted that the rca 36 can receive information from several radius clients but may also gather information directly from the modems by using simple network management protocol snmp commands in reference to fig2 the process implemented in the invention begins when an access request is sent from the radius client to the radius proxy this request which includes the logon and password of the user is then forwarded to the radius server which returns an access accept including the ip address of the user of this session all.
