#require serve killdaemons
#if windows
$ hg clone http://localhost:$HGPORT/ copy
abort: * (glob)

#else
$ hg clone http://localhost:$HGPORT/ copy
abort: error: Connection refused

#endif
$ test -d copy

$ python "$TESTDIR/dumbhttp.py" -p $HGPORT --pid dumb.pid
$ cat dumb.pid >> $DAEMON_PIDS
$ hg clone http://localhost:$HGPORT/foo copy2
abort: HTTP Error 404: * (glob)
