Although it works, it'd be nice if lftp didn't send tons of extra "probe" commands to servers. In some cases, it's the only reliable solution, but if FEAT is reliable for this feature, it'd be good to use it. That way, any later features which FEAT is reliable for can be tested without extra traffic. (However, if there are servers with a feature but that don't list it in FEAT, then it won't work.) Also, if these tests have to be done synchronously, they can slow things down on latent connections. (Of course, the feature can simply be disabled to speed it up, but that's not a very good solution.) -- Glenn Maynard
