[Twisted-Python] [Twisted Newbie] Proxies

[Iggeres Bet]

Dear Twisted List,

I am a Twisted Newbie, searching in the examples
directory I didn't find one sample to guide me how to
use the Spider with a Proxy.

I know it must be a simple solution and I would like
to know that solution.

The spider sample is very simple:

----- o -----
#!/usr/bin/python
  
from twisted.web import spider
from twisted.web import proxy
 
from twisted.internet import app
from twisted.python.util import println
 
a = app.Application("spider")
 
s = spider.SpiderSender("spider", a)
s.addTargets(['http://www.yahoo.com/'])
s.maxDepth = 1
s.notifyDownloadStart = lambda uri:
println('starting', uri)
s.notifyDownloadEnd = lambda uri: println('stopping',
uri)
a.run(save=0)
----- o ----

What is the code to use it beyond a proxy?


Thank You All
Iggeres
