Summary0008898: Reloading TLS/SSL certificates without downtime
DescriptionI was wondering if microhttpd supports hot reload of certificates so I can implement auto-renewal of certificates once the server is running. From what I see we need to provide certificates while starting the mhd daemon. Couldn't find anything regarding changing the certificates while server is running (maybe I missed something). If it is possible can I get some documentation or better yet example? If

You could use MHD_quiesce_daemon() and pass the listen socket to a new daemon with the new certificates. Then stop the old daemon once its connection count drops to 0.
