title: Callback for redirected requests Scrapy
body: <p>I am trying to scrape using scrape framework. Some requests are redirected but the callback function set in the start_requests is not called for these redirected url requests but works fine for the non-redirected ones.</p>
  
  <p>I have the following code in the start_requests function:</p>
  
  <pre><code>for user in users:
      yield scrapy.Request(url=userBaseUrl+str(user['userId']),cookies=cookies,headers=headers,dont_filter=True,callback=self.parse_p)
  </code></pre>
  
  <p>But this self.parse_p is called only for the Non-302 requests.</p>
