Hi!

You cannot "store" the connection object for later use.  You must use it
during the respective callbacks and you may store your own context in the
void** argument of the callback (if needed).

Most importantly, there is no way to put connection objects into a queue ---
the design is such that MHD tells you when you can (and, depending on your
threading model, have to) process connection data.  Putting connections onto a
queue for processing, while theoretically possible with "external select" (but
very hard and I'm not going to show how, that'd be a LOT of work), is not
recommended.

Best,

Christian
