title: Python:requests.exceptions.ConnectionError: ('Connection aborted.', BadStatusLine("''",))
body: <p>I encounter this error when I'm trying to download a lot of pages from a website. The script is pieced up and modified from several other scripts and it seems that I am rather unfamiliar with Python and programming.</p>
  
  <p>The version of Python is 3.4.3 and the version of Requests is 2.7.0.</p>
  
  <p>This is the script:</p>
  
  <pre><code>import requests
  from bs4 import BeautifulSoup
  import os.path
  
  s = requests.session()
  login_data = {'dest': '/','user': '******', 'pass': '******'}

      downurl=downprefix+str(i)
      r=s.get(downurl,headers=header_info,timeout=30)
      if r.status_code==200:
