Have you looked at the Node.js module Hoxy?

Quick description from the developer's README:

Hoxy is a web-hacking proxy for node.js, intended for use by web developers. Using hoxy, you can act as a "man in the middle" and alter HTTP requests and responses as they flow through, based on a set of conditional rules. As a running process, hoxy otherwise behaves like a standalone proxy server. Hoxy was inspired as a way to complement debuggers like Firebug, which let you manipulate the client runtime but not the underlying HTTP conversation.

This should work pretty well unless you're looking for a lower level, packet to packet inspection of the data.
