title: Get a file from an ASPX webpage using Python
body: <p>I'm trying to download a CSV file from this site, but I keep getting an HTML file when I'm using this piece of code (which used to work until a few weeks ago), or when I'm using wget. </p>
  
  <pre><code>url = "http://.....aspx"
  
  file_name = "%s.csv" % url.split('/')[3]
  u = urllib2.urlopen(url)
  f = open(file_name, 'wb')
  meta = u.info()
  file_size = int(meta.getheaders("Content-Length")[0])
  print "Downloading: %s Bytes: %s" % (file_name, file_size)
  
  file_size_dl = 0
  block_sz = 8192
  while True:
      buffer = u.read(block_sz)
      if not buffer:
          break
  
      file_size_dl += len(buffer)
      f.write(buffer)
      status = r"%10d  [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
      status = status + chr(8)*(len(status)+1)
      print status,
  </code></pre>
  
  <p>How can I get this file again with Python?</p>
  
  <p>Thank you</p>
