I think this would be the expected behavior.  It is stripping the sub-
domain which IIRC is what it should do.  But I am not positive why it is
not stripping the sub-domain on your localhost  test.  Might be the way
your hosts file is set up or it may not strip the sub-domain if it
resolves it from the hosts file but does if it resolves it from DNS.
