Not easily. The proxy classes included with Twisted only really work for 
a simple transparent non-authenticating proxy. Also, twisted.web2.proxy 
was incomplete and didn't work the last time I checked. 
twisted.web.proxy works, but is only compatible with HTTP/1.0 and does 
not allow persistent connections or pipelining.

I am in the process of writing a Twisted-based proxy that supports 
filter plugins (the site is http://xuproxy.sourceforge.net). Currently, 
it is in an alpha state (transparent HTTP proxying with pipelining 
support appears to be fully working, but there may be major bugs 
lurking), so I wouldn't recommend using it for production use.
