Re: [libmicrohttpd] Status 304 and insistent Content-Length header

[Christian Grothoff]

You're right, my reading of the spec is that we SHOULD NOT transmit
content-length in these cases. Should be fixed in SVN 37227.
(Note that if you explicitly add the header, we do send it, we just no
longer add it in if it is missing in these cases.)

Happy hacking!
