This is the first access to Service 2 by the user CSG needs to obtain quota first SvcAuthReq ? CSG Sends SvcAuthReq(UserName, Service 2) to QS SvcAuthRsp ? QS takes a part of the user’s credit (say, €1), converts it to equivalent number of “bytes” (say, 1Meg) and sends SvcAuthResp(UserName, service2, 1Meg) to CSG. GET( ? CSG forwards the original request to the content server, meters traffic on this connection, and keeps deducting from the 1Meg quota. ?

For HTTP persistent connections, a pair of accounting records is generated for each GET. When placed after a proxy (., content engine or WAP gateway), CSG can be configured to use the IP address from the xforwardedfor HTTP h
