title: How to set user-agent in nodejs?
body: <p>I tried this, but I get an error.</p>
  
  <pre><code>http.get({ url: 'http://www.panda.tv/ajax_chatinfo?roomid=89757',
      agent: 'Mozilla/5.0' }, function(res) {
      res.on('data', function(chunk) {
          doSomething();
      });
  });
  </code></pre>
  
  <p>I read the API documentation, but I didn't find anything on how to create.</p>
  
  <p>When I run the code, I get the following error:</p>
  
  <pre><code>_http_client.js:158
      self.agent.addRequest(self, options);
                 ^
