Yeah I have run into some of those problems already. Thanks for pointing that out. You definately need a SIGALRM handler if you are thinking of doing something like this. But I don't really see how switching to Memcached is going to prevent a DOS attack. Not trying to be defensive, just really wondering if there is something I'm not getting about that.
I'm not trying to be offensive either :) I was just warning that putting up a public facing server is eventually going to make you a target. Using a battle tested server will let you concentrate on getting more people to use your app instead of fighting bored 13 year olds trying to bring your server down.
Thanks! I understand your point, but a fork server is so simple I don't think there is much that can go wrong there, if it was serving more data I would be worried, but its meant to do a quick and short reply.
Fork Bombs are easier to pull off from the command line. Not so much with DOS. I would say that loading a large webserver for each request would use up more resources than a tiny C program. Thats the whole point of the post.
Writing your own server in C seems a little crazy anymore. Just use a C++ framework like POCO or ASIO. POCO gives you a fast httpserver component with all the tricky stuff figured out.
