I tried to make aliases w/ trigger but something goes wrong.

Trigger is made on insert in the database. If user logins with

username 123 alias 0123 is created. But if I call 0123 I get

"404 Not found" any idea?

P.S. in ser.cfg I have :

        if (uri==myself) {
                if (method=="REGISTER") {
                        if (!www_authorize("193.193.162.71", "subscriber")) {
                                www_challenge("193.193.162.71", "0");
                                break;
                        };
                        save("location");
