I want to be able to give you a URL and have you resolve it. That
only works if we speak the same transport protocol.
Disagree. The Internet is pretty compelling, so proxies can and do
bridge transport protocols. Applications using the HTTP stack don't
need to know or care about the lower level.
Disagree. HTTP proxies do exist but the only reason that they can work
effectively is that the vast majority of web resources are accessible
through a common medium - namely the public IPv4 Internet and TCP. If
the web were split across several networks with dissimilar
characteristics, it would be much more difficult to arrange seamless
access via proxies.
