Well the HTTP spec doesn't forbid the characters used in ACE, to be sure. But you are tunnelling a new form of information through the legacy protocol, right? As an implementor of a web server, how do I know how to interpret the "host:" field in the HTTP header? If I see something that looks like ACE, I suppose I would need to decode it to the original UTF-8 to compare with my virtual domain definitions. As a WG member, I could probably figure out that I need to do that, but I don't see where that is implied by the specification. Bruce
