7# pop the first line so we only process headers
8_, headers = request_string.split('\r\n', 1)

10# construct a message from the request string
11message = email.message_from_file(StringIO(headers))

13# construct a dictionary containing the headers
14headers = dict(message.items())

16# pretty-print the dictionary of headers
17pprint.pprint(headers, width=160)
