I find it an interesting excersize to read through really old bugs and CvE for http servers to see what might affect my code too. and see how to fix it. nic3 going though =) fun to roll this kind of stuff yourself!
Appreciated indeed. I happened to want to mess around with the C11 concurrency API and write a server of sorts, mostly as a curiosity of how those constructs work out in C coming from C++.
