Re: [libmicrohttpd] Regarding Flow control

[Christian Grothoff]

Hi!

Good news: You don't need to do anything.  MHD will maintain persistent
TCP connections and use TCP's flow control mechanisms automatically.
You can _force_ MHD to not keep connections open by adding "Connection:
Close" to your HTTP response header manually, but by default MHD will do
the right thing.

This is independent of your threading model or the use of suspend/resume.

Happy hacking!
