This is not really a complaint, just a point. Mod_perl when setup right is almost as fast as a C CGI script. Your final section recommended using perl if perl could so the job fast enough, because of the extra security features, or use C otherwise. I disagree - not because I think you are wrong, I jsut feel that your comments are a few years out of date. I suggest that mod_perl should be used if a simple CGI script cannot work fast. I don't suggest this because I am anti-c or pro-perl but because C is much harder to make secure than perl.

When I was a pure C coder (a few years back now) there was some call for using C as a CGI language. In fact, my first forays into web design were written in C. These days I would never consider using C, the thought of reinventing the security wheel every time you write a script, and for no apparent gain doen't appeal to me.

The one thing I really want to point out is this is not an attack on your article.... I wish I had had something like that to read while I was working as a webmaster ;)
