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.

Good luck with your app!

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.

it's not called a forkbomb for nothing

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.

You're right about the webserver being overload. Threads would be less expensive than processes.

I would use Go for this service myself. Defending against abuse is hard whichever way one goes.

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.
