Phill, when you criticize me, it only serves to enhance my reputation. :) > HTTP works fine over non TCP/IP protocols and the ability to do so was pretty important in 1991 when IP was not considered the one true protocol. Yes, HTTP can work fine over other transports. That is however of little relevance to the fact that the vast majority of the web's content is only accessible via IPv4 and TCP. Imagine a not-too-distant world, where there is a significant set of resources accessible only through TCP/IPv4, another set accessible only via TCP/IPv6, and another set accessible via either. In such a world a significant portion of the web's resources would not be accessible by any client that didn't have access to both IPv4 and IPv6, except via a proxy. Proxies could and probably would be set up, but experience seems to indicate that there are enough problems with providing for and locating such proxies to make them seem less than viable as a general solution. > A significant proportion of HTTP traffic takes place over non TCP protocols today. yes, but only as a client-to-proxy protocol. you won't find many web resources hosted on cell phones.
