I'll try to make the spec clearer about this. I guess the real question is whether it should be treated differently from, say, a socket-level error (e.g. "no network interface is up", "no route to host", etc, etc). Seems to me like it shouldn't. Basically, the current proposed Gecko patch treats DNS failure specifically differently from the other possible error status codes (socket errors, out of memory errors, user pressing the stop button, etc, etc). If feel like we should treat all such failures (and non-2xx HTTP responses, since this is the level above the HTTP impl and hence never sees 3xx responses unless redirection failed) identically. Does that make sense? >> Also, that still leaves the question of 2xx responses that aren't >> explicitly mentioned in the spec.

I know, but I just don't think we want a long list of status code checks here that would need to be updated if/when they get added. > For future 2xx codes, I agree that it would > make sense to treat them like 200 OK, so I'll update the spec in due > course. Great. Thanks! -Boris
