Hello List: It would be really great, If I could write something like this in ser.cfg: if (method=="MESSAGE") { if (src_ip==192.168.1.0/24) { route("handle_internal_message"); } else { route("handle_message"); }; }; if (!uri=~myself) { route("handle_other_uri"); }; route["handle_internal_message"] { # code of handle_internal_message }; route["handle_message"] { # code of handle_message }; route["handle_other_uri"] { # code of other_uri }; I think, everybody will agree with me: this way ser.cfg would be more readable and would be easier to write longer script. Its really painful to remember route number. Thanks for reading my posting. MOhammad
