Apache is probably handling the concurrent writes itself. If you want to use syslog, you will need to use appropriate syslog ident and facility and configure your syslog daemon to filter those log messages to a separate file. It won't do that automatically (and doesn't let you log to arbitrary files). Otherwise, I think you'd need to write your own log daemon. - Michael _______________________________________________ Caml-list mailing list.
