[Twisted-Python] how to create a http proxy client in twisted?

[Hoxide Ma]

is there any example?

which example in TwistedDocs\examples\Proxy.py just
like that:

from twisted.internet import reactor
from twisted.web import proxy, server

site =
server.Site(proxy.ReverseProxyResource('www.yahoo.com',
80, '/'))
reactor.listenTCP(8080, site)
reactor.run()

what's that means?
