What I remember was that I pushed for custom ranges and that there was
a lot of push-back from people who thought it was too much complexity.

I think the idea 'sort of' got into the spec, but not fully fleshed out.

I agree that it belongs in the issue list, to either clarify how to
use custom ranges (with a range unit registry, for example) or else
to remove the feature.

Subject: RE: Custom Ranges

I ran into this exact same problem. In the end we choose another approach but the lack of a definition in RFC 2616 on how to extend ranges was a problem. Another big problem is that certain servers (who shall remain nameless) seem to believe that the range values must be integers. I don't see anything in RFC 2616 that seems to require that. But RFC 2616 does seem ambiguous on the subject. This would seem like a good issue for the HTTPBis issue list.

        Thanks,

                Yaron
