Yes.

Don't forget to do your

./configure or your make will fail.

I did a very simple one in perl once, based on a similar SMTP server that someone else had written. Never contemplated doing it in C or C++ though I've written other network server code.

TBH if it's for anything other than the learning experience I'd consider using apache instead, if it's for a custom project you can easily (well more easily than writing your own from scratch) build a cut down / spiffy version with whatever modules you need and hook your own modules in if you need custom functionality.

Either way, I would recommend looking at the apache source code and the Richard W Stevens TCP/IP books,

nginx is also worth a look. Source, About.

I know its not C++ but if you ever need to do anything stupid with a web server just use Node..

Good to see my reply was the most helpful.

I found a sample one somewhere that I modified to my own ends; but it was only a simple single threaded server that supported GET and nothing else. But I plan on replacing it with libwebsockets, which as well as doing web sockets supports http/https requests. Obviously it depends how sophisticated you need it to be.

I write them in REXX, even managed to get a multi-threading one working!

So I decided to use multithreading. Now I problems havtwo e.
