title: nutch: crawling through goagent proxy
body: <p><p>I'm learning crawling pages with Nutch now. But there is a problem that I can't fix.
  I want to crawl pages via a local proxy server, which address is 127.0.0.1:8087. And the server works well(my FireFox can use it well). In the Nutch-conf file conf/nutch-site.xml, I added some properties as follows:<p>
  <strong>http.agent.host-->   127.0.0.1</strong>
  <p>
  <strong>http.proxy.port-->8087</strong><br>
  <p>
  My local server doesn't need any authentication.
  <p>
  Nutch can run successfully but do not request via the proxy.
  <p>
  THANKS.</p>
