Re: [libmicrohttpd] [digest-auth]: responses to POST requests don't get out

[Christian Grothoff]

Dear Andreas,

First of all, which MHD version are you using?  There was a recent fix to nonce 
checking (see ChangeLog) which may help.  

To answer your concrete question, the actual transmission code is mostly in 
src/daemon/connection.c.

Happy hacking,

Christian
