Apparently, with the loacalfile interface and ftp, xmlRequest.status returns 0, and this is the normal behavior with all browsers. It was originally filed as a Mozilla bug, but it has been resolved as invalid. See:
https://bugzilla.mozilla.org/show_bug.cgi?id=331610 and http://groups.google.com/group/mozilla.dev.ajax/browse_thread/thread/0 ffb0e899cd404ff/c02ece139b6eed9a#c02ece139b6eed9a It is suggested to use a compound boolean test for 0 and 200 rather than removing the test altogether.
