            7         This is the mechanism that put entries in /sys/lib/httpd.rewrite
            8         and passwords on the authserver in /sys/lib/httppasswords, which
            9         was awkward to administer.  Instead, use local .httplogin files,
           10         which are implemented in sys/src/cmd/ip/httpd/authorize.c */
