Re: [libmicrohttpd] How to access raw request bytes sent to a request handler (and total request size)?

[Christian Grothoff]

Hi John,

The raw request data is unavailable as MHD processed it in-place
(zero-copy!) to give the parsed headers to the application.

However, it should be relatively easy to modify MHD to just return the
number of bytes in the header, if that would be sufficient?

Happy hacking!
