Implementing an HTTP proxy

Question

I would like to implement and HTTP proxy server to get a deeper understanding of some of the finer points of the protocol and learn some socket programming along the way but I don't want to implement a full-blown HTTP server. What are the relevant RFC pages and sections in those pages that I should be focusing on if I just want to implement a proxy?

The plan is to start with a regular HTTP proxy and then potentially extend it to an HTTPS proxy.

You might also find the work of the HTTPbis group in the IETF helpful; we're re-writing the specs to make them more clear and easier to implement.

See http://trac.tools.ietf.org/wg/httpbis/trac/wiki for more information.
