For a weekend project, I am looking for a micro-web framework such as bottle.py (http://bottlepy.org), but for a simple old C. Sadly, Google didn't help much. Any suggestions are welcome!
After a few more searches, I found libSoup that looks very nice and very easy to use. But beware: libSoup is part of GNOME - so it may not be so micro after all, when it comes to dependencies.
... ehm, I think your weekend has already ended, but here it is: Klone
A few days off later ... I would suggest Kore and Balde (inspired by Flask ).
You need an HTTP server library. I would suggest libonion .
