      • getSessionId

        public static java.lang.String getSessionId​(javax.servlet.http.HttpServletRequest httpServletRequest,
                                            boolean forceSessionCreate)
        Retrieves a session id from the session of given request, handles null-sessions with non stable IDs created locally and stored in request. Sometimes you want to have an ID for logging even for anonymous users, yet not forcing session creation on the container, then this is perfect method to use.
        Parameters:
        httpServletRequest - - to retrieve session id from; no session will be created for this request if there is no existing unless forceSessionCreate is set to true
        forceSessionCreate - - force or not the creation of a session in case there is no existing for current request. If session creation is not forced, then the returned ID is considered unstable between multiple requests.
        Returns:
        either ID of the http-session (if session is available) or a locally created identifier which remains stable for the current servlet-request only. In case the ID is not retrieved from a session, it is prefixed with 'bcd_'.
