Yes, you should be looking at the HTTP1.1 specs instead.
Simplifying a lot, a proxy looks like a web server to the client and
looks like a client to the web server or next proxy up, except that the
client gives a proxy a full URL instead of one relative to the document
root for that (virtual) host. Then throw in complications to do with
connections, resource lifetimes, etc, etc.
