Session management in Restlet or other alternative for that

i am working on restlet application , i am confused at 1 point that how to maintain sessions in restlet application . i google for it but no success .

i found this lines : "The Restlet Framework does not prov开发者_如何学JAVAide any server-side session mechanism in its Restlet API. ..... you must avoid storing conversational state on the server between request/response interactions. Each request should then contain all information needed by the server to process it, without having to refer to out of band information. The Restlet Framework will help you to enforce this rule."

how can i make this possible ? any idea !!!
