I found 4.3.2 particularly interesting, as there doesn't seem to have been consensus in this space in the past. For example, the ws(s) and ipp(s) schemes made a different decision. I presume your assertion is that, were we defining these protocols today, they would be using http(s) instead? I don't see anything wrong with that; I just want to probe the edges of this advice by seeing how it would have applied to decisions we made in the past, since that's a pretty good predictor for how it might apply in the future. The advice in 4.3.3 seems a bit strong, in that it will require whatever process listens on port 443 to take on an ever-increasing role. If we're going to keep this advice, I think the document needs some treatment of the software architecture implications: functionally, whatever listens to port 443 will need to be able to delegate sub-trees of the URL space to other processes. I know that some web servers have mechanisms to handle this kind of thing today; but we're effectively saying that this will become required base functionality for web servers moving forward. I wonder, in that context, whether the current advice strikes the right balance. /a On 7/11/17 06:14, Mark Nottingham wrote: > A number of folks have recently noted that BCP56 addresses the problems of using HTTP for protocols in the early 2000's, but we've moved on considerably since then. > > Given the number of IETF protocols being build upon HTTP these days, it seems timely to reconsider it.
