阅读scrapy文档后，我认为HttpProxyMiddleware默认情况下启用。 但是，当我开始通过scrapyd的Web服务接口蜘蛛，HttpProxyMiddleware未启用。 我收到以下的输出：
2013-02-18 23:51:01+1300 [scrapy] INFO: Scrapy 0.17.0-120-gf293d08 started (bot: pde)

2013-02-18 23:51:02+1300 [shotgunsupplements] INFO: Spider opened
需要注意的是HttpProxyMiddleware未启用。 我怎样才能启用它scrapyd？ 任何帮助将不胜感激。
我scrapy.cfg

default = pd.settings
[deploy]

我有以下settings.py

NEWSPIDER_MODULE = 'pd.spiders'

TELNETCONSOLE_PORT = '6073' # only we can see it.
TELNETCONSOLE_ENABLED = False

LOG_ENABLED = True
ROBOTSTXT_OBEY = False
ITEM_PIPELINES = [
