Re: [libmicrohttpd] large incremental responses

[Evgeny Grin]

Hi Erik,

You need to create response by MHD_create_response_from_callback(). Use 
'MHD_SIZE_UNKNOWN' if size is not known in advance.
When data callback is called by MHD, provide all data you have at that 
moment (but not more than requested by MHD of course). If you don't have 
any data available call MHD_suspend_connection().
Later, when you get new portion of data ready to send, call 
MHD_resume_connection() then data callback will be called automatically 
by MHD.

Does it suit your needs?
