I've been reminded privately that there may be cases where other implementations don't always behave this way. The *MIT* implementation does follow the RFC spec in this, and will always use lowercase host names. There are also cases having to do with new specifications in the works where, depending on a site's configuration, getting the case exactly correct may be less critical. Again, at the moment, that doesn't really affect the MIT implementation.
