Understood, without direct access to the system, and a wealth of information, we can't answer that question for you. There is probably some identifying information there, but you can't tell us what it is and we can't look for it, so our hands are tied. I have developed systems in the past where I glob the user agent and some other headers from clients and hash those to use as an identifier. The same browser will produce the same identifier, and can be used to identify the user in absence of anything else. But I don't know what headers or other details are in your HTTP requests. I don't know what there is to work with. Anyway, good luck! --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
