mini_httpd is a small HTTP server. Its performance is not great, but for low or medium traffic sites it's quite adequate. It implements all the basic features of an HTTP server.

Haserl is a small program that uses shell or Lua script to create cgi web scripts. It is intended for environments where PHP or ruby are too big.
