Thanks.
Great.
With GET/HEAD will keep-alive work, too?

Yes.

That MHD does not send "100 CONTINUE" if the protocol is HTTP/1.1 and
the client asked for 100 CONTINUE.  So if you queue the error message
immediately (during PUT/POST), you avoid the traffic upload from the client.

For GET/HEAD requests, it makes no difference whatsoever (you can even
queue 200 OK instantly without complications).

Happy hacking!
