Re: [libmicrohttpd] MHD threading models: what model is similar to Least Connected?

Master,

I'm going to test it in C simulating my scenario (in Pascal), the idea using a list of daemons is really awesome.

Thanks a lot for the full example, I probably will be back with some news! :-)

You will need something like:

  daemons[N++] = MHD_start_daemon (MHD_USE_NO_LISTEN_SOCKET |

        daemons[N++] = MHD_start_daemon (MHD_USE_NO_LISTEN_SOCKET |

      n++; /* Switch to next worker */
      if (MAX_DAEMONS == n)
      {
        n = 0; /* Return processing to first daemon */
      }
    }
    MHD_add_connection (daemons[n], fd, &addr, &addrlen);
  }
-----------------

"Slow" daemons will continue processing their connections, when slowdown
is detected, you will switch new connections to next daemon.
