Hi Qihao: The idea of identifying a user from a pre-defined, hard-coded url to username map would work. However a more automatic way is for a client to find out who he/she is after logging on to the provenance server. Is there a cookie or query mechanism that we can leverage? The login mechanism you use may provide some programming interface.
