C is not good at web development? Most of the "web" stack is written in C: OS/NGINX/apache/php/java/perl.
If you do write the top of the stack in C, it will run faster than anything else and be smaller. This means lower turnaround time which is VERY IMPORTANT in web apps. C, in many cases, is the best Web language.
Perhaps there's a misunderstanding in the term "turnaround". I meant it in this sense t = x + y + z.
where t = total time, x = send time , y = processing time, z = send back to user time. If you can decrease y, you decrease "t". Responsiveness is important to users. With the advent of large and extremely fast memory cache, small program size will dramatically increase program execution speed by have small code and small data already in cache. Smaller program executable will enable many more instances on a real physical node. Size matters. Speed matters.
I wrote a CGI in C around 2005. The C code produced only a small about of XML. All the presentation layers were done using client-side XSLT, CSS, and a bit of javascript. The result was very portable and efficient: we had to support serving from z/OS mainframes that used EBCDIC, AIX, HP-UX, Solaris, Linux, and Windows.
