# httpd

httpd is a simple web server which only does HTTP.  This is just a research

project for tiny programs and Unix way of live.  The main idea behind this

project is, to write a daemon that just implements the handling one protocol.

**This daemon is NOT for productive use**

 * missing security features!

 * no stable code base!

## Don'ts:

 * no IPv4 and IPv6

 * no SSL and TLS

 * no fastcgi

## Ideas:

 * UNIX Client-Server Program Interface (UCSPI)

 * protocol parsing with regex(3)

 * CGI scripts over file execution permissions

 * authentication over file others permissions and bsd-auth(3)

## expected problems

 * bad performance on large scale

 * bad latency

 * bad performance on many parallel requests

## expected improvements

 * lesser amount of source code

 * simpler source code

 * lesser maintenance

## Tested on

 * OpenBSD current

 * GNU/Linux (Debian)

  * with package: libbsd-dev

  * without authentication
