Re: [libmicrohttpd] How to avoid the "Internal application error, closin

I don't know anything about using external loggers with MHD and this isn't really any of my business, but filtering log messages based on the string seems like a bad idea.  That string could change in future releases (plus I guess you're doing extra string comparisons, but I doubt that amounts to very much).

If MHD doesn't provide some kind of 'message code' or a #define constant for the string (so you could compare it to something consistent), then maybe you could just log an extra message before you return MHD_NO?  E.g., "Ignore the following message - there is no error - connection was intentionally refused."

Maybe it's just me, but I always try to promote easy maintenance and avoid fragility whenever it's reasonably possible.  This seems like one of those times, albeit for a pretty minor thing.

Hm... I use MHD_OPTION_EXTERNAL_LOGGER, so I'll do something like:

if (msg != 'Internal application error, closing connection.\n')

I thought about it, but I didn't know that I could skip all messages of this type.

Thank you! :-)
