This doesn't seem to be a concern of this (draft) standard. HTTP Host: is well
standardized and defined. You should solve this there, in your webserver/proxy.
This is just sensible layering of protocols. You should strive to solve the
problems in the correct layer. Sometimes a little layering violation is still
the lesser of evils, but I really don't think that applies here. *Especially*
with IDN! That only makes it worse. How many independent IDN implementations in
how many layers do you want to add?
