[libmicrohttpd] Queuing responses?

[Glenn]

Following up on today's digest ---

I'm going through the libmicrohttpd tutorial and working through the examples. 
One question that comes to my mind is why the second invocation of the 
connection handler is necessary/desirable. In the tutorial it is stated: "This 
is because the content of the message body will not be received if a response 
is queued in the first iteration. Furthermore, the connection will be closed 
right after the response has be transferred then." Apparently I'm missing 
something. Can someone supply details (or a pointer to where this has already 
been discussed) as to the requests and responses that MHD is going through?
