I was saying that if an empty string is returned, then it means that the header exists and is empty.  An example was "User-Agent: \r\n".
And my remark "I believe None is better." concerned your initial question "Should the field be totally absent [...]" regarding how to deal with a header that does not exist.

Therefore, "User-Agent: \r\n" becomes a real '', not None.  None is only when the User-Agent: header field is absent from the headers.

Yes Antoine, thanks!
