Re: [libmicrohttpd] Abort POST request in libmicrohttpd

[Christian Grothoff]

Yes, you can simply queue any response. As long as you do this on the
_first_ callback to the access handler (and as long as the client
expected "100 continue"), this will provide a proper error message and
prevent the upload.

Happy hacking!
