open-source HTTP proxies written in python

A list of open-source HTTP proxies written in python
for future reference, here is a list of a bunch of open source proxies written in python.

A HTTP proxy is a piece of software that acts as an intermediary between HTTP client software (i.e. browser) and HTTP server software. The proxy receives all requests from the browser, and relays them (possibly modified) onto the server. Likewise, it receives all responses from the server, and relays them (possibly modified) to the client. HTTP Proxies can be used for a wide variety of tasks, including filtering, logging, caching, etc, etc, etc. At some stage, most web programmers will make use of some form of proxy.
