Is there a source code for any web server preparations under *nix in C?

Question

C++ / C#

Maybe someone knows some small project, an example-blank, of a web server daemon, open source, written in C. By minimalistic, I mean the following functionalities:

1. Forming and issuing an http header
2. Function \ its preparation for displaying the "body" of the page from RAM
3. Receiving data via get \ post
4. Sessions

As an option - some kind of cumbersome C library , for working with HTTP.

Offer and options that do not fit into my requirements, but may partially coincide with them.

Thank you all in advance for your replies!

Answer 1

Try this one: onehttpd

Answer 2

0w.ru/httpd/
Very small, very smart. At one time, in narrow circles, it was considered "Mail.ru's answer to Rambler's nginx."

Answer 3

Try Mongoose again.

Answer 4

micro_httpd
Just for fun, but quite a working server in 250 lines.

Answer 5

nginx, though not in C
