[Twisted-Python] Status of current proxy support (of various kinds)

[Damiano ALBANI]

Hello,

I'm trying to determine the current status of proxy support in Twisted.
I've googled quite a bit to find an answer but I couldn't get a crystal
clear picture.
What I mean by "proxy support" is the capability to:
  - act as a proxy server
  - use an external proxy server (i.e. act as a client)
And by proxy, I'm talking in pratice of SOCKS v{4(a),5} and HTTP "CONNECT"
standards.
